Creamy White Chili

My husband does not care for regular chili, but loves this. It is adapted from a recipe I found in Taste of Home a few years ago.

1 pound boneless skinless chicken, cubed or shredded
1 medium onion, chopped
1 1/2 tsp garlic powder
1 Tbsp oil
2 cans (15 1/2 oz each) great northern beans, rinsed and drained
1 3/4 cups chicken broth
2 cans (4 oz each) chopped green chilies
1 tsp salt
1 tsp cumin
1 tsp oregano
1/2 tsp pepper
1/4 tsp cayenne pepper
1 cup sour cream
1/2 cup whipping cream

In a large saucepan, saute chicken, onion, and garlic powder in oil until chicken is no longer pink. Add the beans, broth, chilies, and seasonings. Bring to a boil. Reduce heat and simmer uncovered for about 20-30 minutes. Remove from heat and stir in sour cream and whipping cream.
