Chicken Taco Chili

8 Servings, about 200 calories each 1 can black beans 1 can kidney beans 1 can corn kernels 1 small can diced tomatoes with green chilies 16 oz tomato sauce 28 oz diced tomatoes packet taco seasoning 1 Tbsp chili powder 3 boneless chicken breasts Cook 6 hours high or 10 hours low in the crock pot. Note: I used mild chilies. Choose your own hotness. A dollop of sour cream on top is quite tasty.
