Pizza can be a healthy, easy choice from your own oven. Preheat oven to 350 F. Lightly coat a baking pan with cooking spray. Spread 1/2 cup chunky tomato sauce over 6-inch pre-made pizza crust. Top with 1 slice onion, 4 slices red bell pepper, 1/4 cup shredded low-fat mozzarella cheese and 2 tablespoons chopped fresh basil. Place the pizza on the baking pan and bake until the cheese is melted and golden brown, 5 to 7 minutes.
