Mix sauce ingredients in a small pan and simmer for 1 to 2 minutes. Place pitas on a cookie sheet, bottom side up. Spread the sauce on the pitas. Then sprinkle with the grated mozzarella. Distribute toppings over the cheese. Bake for 5 to 10 minutes until cheese is melted and toppings are browned. *Topping Suggestions: Thinly sliced vegetables (green bell peppers, red bell peppers, mushrooms, onions), black olives, anchovies, pepperoni, diced ham or whatever your family likes. For a memorable and easy children’s birthday party, have the sauce, cheese and an assortment of toppings ready and let each child make his or her own pizza. Pita Pizza parties are always a big hit.
