Roasted Tomato Pizza:  Brush a cookie sheet with oil.  Lay tomatoes sliced 3/8-1/2" thick on the cookie sheet.  Brush with olive oil and dust with garlic powder and bake about 1/2 hr at 350 deg. until they start to dry out a little.  When the pizza crusts are ready, carefully move the tomato slices with a pancake flipper and arrange to nearly cover the pizza.  Sprinkle a small amount of grated mozzarella on top and then top with vegetables sauteed slightly in olive oil with garlic  (suggestions: peppers, zucchini, mushrooms, and onions).  One can also add a little blue or gorgonzola cheese to the vegies.
