2 lb. ground beef
1 stick (4 tbsp.) butter
1 onion, chopped
1 (10 3/4 oz.) can cream of mushroom soup
1 (10 3/4 oz.) can cream of chicken soup
1 (8 oz.) can taco sauce
1 (10 oz.) can enchilada sauce
2 c. Cheddar cheese, grated

Preheat oven to 350 degrees. Brown ground beef in skillet. Saute onion in the butter. Add sauces and soups to the onion and meat mixture. Layer the meat mixture and tortillas in a large casserole and top with grated cheese. Bake at 350 degrees for approximately 30 minutes.

Tortillas can be torn into fourths and added to the meat mixture instead of layering. Bake as above.
