Creamy white chicken chili

1 lb boneless, skinless chicken (depending on how much time I have, I sometimes just used canned chicken)
1 1/2 t. garlic powder
1 T. oil
1 med onion, diced (I have also just used onion flakes)
2 cans Great northern beans, rinsed and drained
1 can chicken broth
2 cans (4 oz) diced green chilies
1 t. cumin
dash of salt and pepper
1 t. oregano
1/4 t. cayenne pepper
1/2 C. whipping cream
1 C. sour cream
Saute chicken, onion, and garlic powder in oil. Add beans, broth, chilies, and seasonings. Bring to a boil. Reduce heat. Stir in sour cream and whipping cream. Serve with tortilla chips. (Add sour cream and whip cream about 1/2 hour before serving)

-I know it looks like a lot of ingredients, but it's mostly spices. This is such an easy recipie that doesn't take a lot of time, and tastes really good. It isn't really spicy, but I have made it without the cayenne pepper before when I had people over, just to MAKE SURE it wasn't spicy.
