Preheat oven to 250° F. Heat pita breads in preheated oven for about 5 minutes, or until slightly browned. Meanwhile, in a large bowl combine the chicken, lettuce, onion, cheese, mayonnaise, ketchup, chili sauce, hot pepper sauce, lemon juice and ground black pepper. Mix well. Slice hot pita breads around the edges to form pockets; fill bread pockets with chicken mixture. Serve hot. Makes 2 to 4 servings |
