Whole wheat pita pizzas @ the Chill Zone

For this past weekend’s Chill Zone, the kids prepared themselves mini toaster oven pizzas with leftover whole wheat pita bread rounds from our prior session, tomato sauce, shredded mozzarella, oregano, red pepper flakes (for those who like a little spice), and chopped up veggies like green bell pepper and onion.

Using a toaster oven did pose some challenges. Because of its small size, our oven could only fit one pizza at a time, requiring much patience amongst the kids.

Beyond this, we had the minor issue of some pizzas sticking to the baking sheet. For those looking to make this snack at home, we suggest either 1) pre-baking a pita round, lightly brushed with olive oil (results in a crispier crust) or 2) using a non-stick spray on the pan. A little sprinkle of cornmeal on the pan can help prevent sticking, too, since it slightly “lifts” the crust off the pan.

A simple yet classic snack idea that seemed to go over quite well with the bunch!

Learning the Parts of a Plant

Getting our hands dirty

Cold winds and a recent snow shower didn’t deter Stanley Garden Club from meeting last week and getting even more seeds planted, though the chilly temperature did keep us indoors. We got our hands dirty as we added some water to the dried up potting soil, creating the moist foundation needed for seed germination. We then planted beets, eggplant, peppers, and both red and yellow onions. There were several different kinds of beets, including golden beets, which were easily identifiable by their golden seeds- how convenient! We will definitely have to do some beet taste-testing come harvest time. Will the golden and red varieties taste similar or different?

Because of the cold weather and the fragility of new seeds, we planted these tender vegetables in plug trays. A plug tray is great for the very first stage of a plant’s life; it contains many rows of individual cells which help keep young roots separated. However, once the plants begin to grow we will have to transplant them from the plug trays into bigger trays, and then into the garden beds outside.

After washing our hands off we had a great discussion about the different parts of a plant, and how vegetables can come from just about any one (or more) of these parts. Important features of any plant include the root, stem, leaf, and flower (which develops into the fruit, which contains the seeds- two more plant parts!). Each part has a distinct and important role. Roots absorb water and nutrients from the soil and keep the plant from blowing away. Plants can have either a taproot system, in which there is one primary thick root that goes straight down into the ground, or a fibrous root system, in which there are many thin roots spreading out in every direction. Carrots and beets are examples of root vegetables, or more specifically, taproot vegetables.

Root veggies

The water and nutrients taken up by the roots are then transported up through the stem. But the stem is not just a way for the plant to move around nutrients; it also serves the important role of bringing the leaves closer to the sun. Unlike animals that must find their food, plants make their own food by using energy from sunlight to convert carbon dioxide into glucose (a type of sugar) while also releasing oxygen into the atmosphere. This process is called photosynthesis. The leaves of the plant are the primary actors in photosynthesis; they hold the most chlorophyll (green pigment) that is necessary for the plant to absorb sunlight. While all plants have leaves, some examples of leafy vegetables (crops we grow specifically for their leaves) include lettuce and spinach.

Another key part of a plant- but something we don’t usually associate with vegetables- is the flower. One example of a flower vegetable is, believe it or not, broccoli! Flowers are attractive to insects like butterflies and bees; enticed by their color and scent, these organisms feed on the flower’s nectar and, without knowing it, transfer pollen so that fertilization (when the sperm and ovules, or eggs, join together) can occur. A protective shell (the fruit) then grows around the developing seeds. Some plants make this fleshy layer extra delicious to encourage animals to eat the fruit and spread its seeds after defecating, which is simply a fancy word for pooping! Many foods we consider vegetables in culinary (cooking) terms are technically fruits because they contain seeds*. Some fruits we typically call “vegetables” include cucumbers, tomatoes, and squashes.

*Botanically speaking, a fruit is the fleshy part of a flowering plant derived from the fertilization of the plant’s ovaries; however, it is more generally considered to be the part of a plant that holds its seeds, such as bean pods.

Food Memories and Family Dinners

Read our latest column in the Waltham News Tribune!  “Food Memories and Family Dinners,” by Leslie Glynn, appeared in the Waltham News Tribune on March 22, 2011.  Leslie describes the enjoyment of food and family time, and the importance of keeping these rituals alive today.  She also shares one of her family recipes, “Pasta e Fagiole” (Pasta and Beans).

Vermicomposting @ Brandeis

And now for a quick break from Healthy Waltham’s youth programming for a glimpse into college life at Brandeis University. Although the worm composting unit has just finished at McDevitt Middle School, it’s just now beginning at Brandeis. Through the Brandeis Sustainability Fund, I’ve set up two worm composting bins in Brandeis residence halls (affectionately called dorms). Originally, I wanted to set up bins similar to those we had in the classrooms at McDevitt: simple, inexpensive Rubbermaid bins with holes drilled in for ventilation. However, the Brandeis administration and facility staff decided they would only be comfortable supporting this initiative if we used bins specifically designed for the purpose of vermicomposting. Running with the mentality that any worms are better than no worms, I went ahead and purchased two Worm Factory bins, along with a pound of red wigglers (about 1,000 worms total). These bins include multiple trays; once one try is filled with castings, you can add another fresh tray of food scraps so that the worms will migrate upwards while finished compost from the first tray can be harvested. They also come with spigots for controlling extra moisture that can be used as nutrient-rich compost tea (the liquid portion of compost) in your garden. While both of these features are interesting and helpful, neither are necessary for at-home worm composting.

The bins are now set up on two dormitory floors. How will these bins fare compared to our bins at McDevitt Middle School? Will a more expensive system actually provide any advantages? Check back for updates!

Vegetable-Tofu Stir Fry @ the Chill Zone

“Stir fry? I love stir fry!” The shouts rang out as youth hanging out at the Chill Zone this past Saturday gathered in the snack room to cook up some stir fry. However, much of the excitement quickly turned to confusion as students realized there was no chicken to be found.

“Wait… stir fry without chicken? What?!” They asked in shock. So began an introduction to the wonders of tofu.

Tofu is made of soy beans, and is often used by vegetarians (and non-vegetarians!) as a replacement for meat in a variety of dishes. It has a spongy texture– we had lots of fun squishing it with our fingers– which is great for soaking up lots of flavor. If you choose to eat less meat in your diet, protein-rich foods like tofu are essential to keeping your body healthy and happy. But the wonders of tofu and soy beans don’t stop at replacing meat: soy products can also be used to replace milk, cream cheese, yogurt, and even ice cream!

Some Chill Zone participants were pretty skeptical that the tofu would make a tasty meat replacement. But despite their raised eyebrows, everyone helped prepare the meal by chopping up lots of different vegetables. A great veggie stir fry can be made with just about any vegetable combination, but there are a few basic ingredients, such as onion and garlic, that you should keep in mind when getting started. After frying up some of these alliums in our electric wok (and a little ginger, for good measure), we added the tofu and waited as it became golden brown. We then added carrots, broccoli, and red pepper, and also made a separate batch with mushrooms. As we waited for the veggies to cook we mixed up a scrumptious sauce of honey, rice vinegar, and soy sauce to pour on top of our stir fry. The final product: delicious! I think we may have even had some tofu-converts.

After chowing down on our stir fry, we had an herb and spice smell test. Following up on last week’s discussion of parts of a plant and flavorings, the kids were excited to test their knowledge and get a little more familiar with the dried herbs and spices I brought in from home. By the end of our session, the guys were spice experts, easily telling basil from oregano and nutmeg from cumin with only the slightest sniff.
