Chicken Tortilla Casserole - cooking recipe

Ingredients

1 lb boneless skinless chicken breast, cut up
1 can diced green chilis
1 small onion, diced
3 cups shredded cheddar cheese
1 can cream of chicken soup
1/4 cup milk
1/4 teaspoon garlic powder
3/4 teaspoon chili powder
1/2 teaspoon cumin
8 flour tortillas
sour cream
salsa

Preparation

Brown chicken, set aside.
Saute onions in butter until transparent.
Mix soup, milk and spices.
Starting with flour tortillas, layer ingredients (tortillas, soup mixture, chicken, onions, chilies, then cheese. Repeat layers, ending with cheese) in a round 2 qt size casserole dish -- I have tried it in a square pan and it does not come out as well.
Bake at 350 oven for 45 minutes.
Serve with salsa and sour cream.
