White Chicken Chili

I got this from a friend who used to live in our ward.  I really love it!

1 lb boneless, skinless chicken breasts, cut into 1/2 inch pieces
1 medium onion, chopped
1 1/2 tsp. garlic powder
1 TB oil
2 cans Great Northern beans, rinsed and drained (15 oz. each)
1 can (14 1/2 oz) chicken broth
2 cans (4 oz each) chopped green chilies--I only use one
1 tsp salt
1 tsp ground cumin
1 tsp dried oregano
1/2 tsp pepper
1/4 tsp cayenne pepper
1 cup sour cream
1/2 c. cream


In a large saucepan, saute chicken, onion, and garlic powder in oil until chicken is no longer pink.  Add beans, broth, chilies, and seasonings.  Bring to a boil, reduce heat, simmer uncovered for 30 minutes.  Remove from hear, stir in sour cream and cream.  Serve immediately. 

(If you are in a hurry you can boil the chicken, then cut it up and put everything in a crockpot except the sour cream and cream).
