Start by placing the chicken breasts at the bottom of the slow cooker.
In a mixing bowl, combine the black beans, corn, diced tomatoes (with their juices), tomato paste, onion, garlic, chicken broth, taco seasoning, and cumin. Stir until well blended.
Pour the mixture over the chicken in the slow cooker, ensuring the chicken is covered.
Season with salt and pepper according to your taste preference.
Cover the slow cooker and set it on low for 6-8 hours or high for 3-4 hours.
Once cooking time is complete, shred the chicken using two forks and stir it back into the soup.
Serve hot, topped with fresh cilantro, a dollop of sour cream, and a sprinkle of shredded cheese.
Notes
Serve with fresh cilantro, sour cream, and shredded cheese for added flavor.
