For a quick meal, I like to keep a frozen cheese pizza in the freezer, one made with whole-wheat crust — I like Kashi and Newman's Own the best. It's a little boring as it is, and doesn't contain much fiber or vitamins, so I like to make it a little healthier by adding my own veggies. I chop up some mushrooms, spinach, peppers, carrots, zucchini, broccoli, or whatever I have in the fridge. I sauté them with fresh herbs, garlic, and olive oil, spread them on top of the pizza and bake it as usual. Not only is it more flavorful and full of interesting texture, but it's also more filling, so I end up eating fewer slices.
