Add everything to the Crock Pot: Place chicken breasts, beans, corn, tomatoes, onion, spices, and broth into your slow cooker. Stir lightly.
Set and cook: Cover and cook on LOW for 6–8 hours or HIGH for 3–4 hours, until the chicken is tender.
Shred the chicken: Remove the chicken, shred with two forks, and return it to the soup.
Simmer and blend flavors: Let it cook another 15 minutes so the shredded chicken soaks up the spices.
Serve and enjoy: Ladle into bowls and top with cheese, avocado, lime, and tortilla chips.
