Combine soup, tomatoes with chiles, sweet pepper, onion, chili powder, and black pepper; set aside.

To assemble, sprinkle about one-third of the tortilla strips over the bottom of an ungreased 13x9x2-inch baking dish or 3-quart rectangular casserole. Layer half of the chicken over tortilla strips; spoon half of soup mixture on top. Sprinkle half of the cheese and another one-third of the tortilla strips over the soup mixture. Layer with remaining chicken, soup mixture, and tortilla strips.

Bake, uncovered, in 350 degree F oven about 45 minutes or until bubbly around edges and center is hot. Remove from oven; sprinkle with remaining cheese. Let stand 10 minutes before serving. If desired, top with sliced tomatoes and green onions. Makes 8 servings.

Cover tightly after sprinkling with cheese. Transport in an insulated carrier. If desired, trasnport tomatoes and green onions in an insulated cooler with ice packs.

About 1 pound boneless chicken breasts will yield 3 cups cubed cooked chicken; 1/2 pound yields about 1-1/2 cups cubed cooked chicken

Prepare using method above, except assemble in an ungreased 2-quart square baking dish. Bake, uncovered, in a 350 degree F oven about 35 minutes or until bubbly around edges and center is hot.
