Sour Cream Chicken Enchiladas

This recipe can be prepared ahead of time, double wrapped and frozen. I'm thinking it would be easy to double the recipe and freeze one.

Ingredients:
2 chicken breasts, approx. 1#
1 medium onion, chopped
2-3 Tbs olive oil
1 can black or kidney beans
Cumin, to taste
Chili powder, to taste
6-8 tortillas
1.5c shredded Montery Jack or Mexican cheese
1/4c butter
1/4c flour
1 - 15oz can of chicken broth
1c sour cream
1 - 4oz can diced green chilis

Preheat oven to 400*
Heat olive oil in a pan. Dice the chicken, season with salt, pepper, cumin and chili powder. Cook chicken with the onion until just done. Remove from heat. Add beans and corn and mix together. Spray a 9x13 inch pan with nonstick spray or olive oil. Put the chicken mixture in each tortilla with a sprinkle of cheese and place in the pan seam side down.

Melt the butter and add flour to create a roux. Cook for 2-3 minutes, slowly whisk in the chicken broth to create a thickened sauce. Take off heat and stir in sour cream and chilis. Pour over enchiladas and top with remainder of the cheese.

Bake for 20 minutes until cheese topping in melted.
