PREPARATION:

1. Preheat oven to 450°F. Roll out each loaf on lightly floured surface into 15-inch circle; press each into greased 15-inch pizza pan or stretch into 15X10-inch baking pan. Crimp edges to form rim; prick several times with fork. Bake crusts 10 minutes. Remove from oven; set aside.
2. Reduce oven temperature to 400°F. Heat oil in large skillet over medium-high heat until hot. Add onions and garlic; cook and stir 6 to 8 minutes or until onions are tender. Divide onion mixture (including olive oil) between crusts. Arrange tomato slices evenly over onion mixture. Sprinkle each pizza with 1/2 teaspoon basil leaves, 1/2 teaspoon oregano leaves and black pepper to taste. Sprinkle each pizza with 1/2 cup Parmesan cheese. Top with olives and desired amount of bell peppers. Bake 10 to 15 minutes or until toppings are heated through.
