Got this recipe from a church member years ago. I have made it many times and always pleased with the results. This casserole is great with a veggie loaded salad! Also a dollop of sour cream and since this is a lighter version, I would go with light sour cream or fat free.
Saute onion and bell pepper in a large skillet coated with cooking spray over medium-high heat 5 mintues or until tender. stir in chicken,soups, diced tomato and green chilies, chili powder, pepper, garlic powder: rmove from heat. Tear tortillas into 1-inch pieces: layer one third tortilla pieces in bottom of a 13x9-inch baking dish coated with cooking spray. Top with one third chicken mixture and one third cheese. Repeat layers twice. Bake at 350F for 30-35 mintues or until bubbly. Makes 8 servings.
If you like a little heat, add a touch of cayenne pepper
