This is one of our family favorites. The original recipe came from a can of Rotel. I've made a few changes.
5 chicken breasts, cooked and cut up (I prefer to dice and then brown in a skillet)
1/2 onion, chopped
1 can cream of mushroom soup
1 can cream of chicken soup
1 can Rotel
1 large green pepper, chopped
1 ½ tsp chili powder
1 pkg corn tortillas, cut into pieces
½ lb grated cheddar cheese
Combine chicken, onion, soups, Rotel, green pepper and spices. Layer corn tortillas on bottom of greased casserole dish, then layer chicken mixture, and then cheese. Repeat. Bake @ 350 for 35 minutes.
