PREPARATION:
- Preheat oven to 375°F. Combine tomatoes, onion, bell pepper, 2 tablespoons water, garlic, Italian seasoning and sugar in 2-quart saucepan. Bring to a boil over medium-high heat. Reduce heat to medium-low. Cover; simmer 8 to 10 minutes or until onion is tender.
- Combine remaining 4 tablespoons water and cornstarch in small bowl; add to tomato mixture. Cook and stir until mixture boils and thickens. Cook and stir 2 minutes more.
- Meanwhile, place pita bread halves on ungreased baking sheets. Bake 8 to 10 minutes or until edges just start to brown.
- Spread vegetable mixture over pita bread halves. Sprinkle with mozzarella, Cheddar and Parmesan cheeses. Bake about 5 minutes more or until cheeses melt and pizzas are heated through.
