Play with the seasonings as you like. If you like it spicier add more chilies and/or cayenne. If I were making fajitas I would add lime juice and onion powder so it's nearly the same chicken meat and you could use the same here
White Chicken Chili
1 pound boneless skinless chicken breasts
1-1/2 t cumin
1/2 t salt
1/4 t pepper
1/2 cup diced onion
2 - 15 ounce cans Great Northern beans (white), undrained
2 cups chicken broth
4 ounce can green chilies, undrained
up to 1/2 cup sour cream
In a medium bowl add about 1/2 Tablespoon of olive oil, seasonings, and chicken. Turn to mix and coat. For best flavor grill chicken. Cut into nice size chunks.
Meanwhile, cook onions in a little bit of olive oil until soft. Add broth and beans.Stir in chunked chicken and cook for 20 minutes. This will soften the beans a bit more and thicken your soup.
Stir in sour cream.
To serve, top with tortilla strips and more sour cream if you like.
