Rummage the pantry, because you will need:
1 large onion, chopped
1 16-ounce can black beans
1 16-ounce can kidney beans
1 16-ounce bag frozen corn
1 8-ounce can tomato sauce
2 14.5-ounce cans diced tomates with chili peppers
1 packet taco seasoning
2 boneless, skinless chicken breasts
Dump all the ingredients, except the chicken into your crockpot. Stir it all up, and lay the chicken breasts on top of the mixture. Cover, and crock it all day. Just before serving, fish out the chicken, and shred it up with a fork. Stir it all together, and serve with shredded cheese.
Dinner is done!
