Souper Chicken Enchilada Casserole

We eat this at least twice a month. It is one of our favorites. 

1 can Cream of Chicken Soup

½ cup sour cream
1 small onion, chopped
1 tsp. chili powder
2 cups chicken (cooked & chopped)
8 flour tortillas (cut into strips for lasagna style casserole)
1 cup shredded cheese
Combine soup, sour cream, and chili powder. Mix well and then add onion and chicken. Then roll into tortillas OR I like to layer it  lasagna style , layer mixture, tortilla strips and cheese (repeat) making sure to have cheese on the top.
Bake 350 F for 25 minutes. (1 can of chopped green chilies may also be added to the mixture).
