I'm not sure if this is officially "Mexican", but when I'm in the mood for it, IT COUNTS! There are a lot of recipes for this out there. This one is pretty easy and fast. Plus it's very tasty! Serve with beans and tortilla chips.
1 can of cream of mushroom soup
1 can of cream of chicken soup
1 4 ounce can of Ro-Tel
2 1/2 cups boiled chicken breast chopped
10 corn tortillas cut into fourths
12 ounces of shredded cheddar cheese
Mix together and heat the soups, Ro-Tel, and chicken. In a 3 quart buttered casserole dish, place a layer of tortillas, a layer of soup mixture and a layer of grated cheese. Repeat. Bake at 350 degrees F for 30 minutes.
