Begin by dicing the onion, bell pepper, and mincing the garlic. Set aside.
Place the chicken breasts at the bottom of the slow cooker.
Add the diced onion, bell pepper, and minced garlic on top of the chicken.
Pour in the black beans, corn, and diced tomatoes with their juices.
Add the chicken broth, chili powder, cumin, paprika, salt, and pepper. Stir everything gently to combine.
Cover the slow cooker and set it on low for 6 hours.
Once the cooking time is complete, remove the chicken breasts from the slow cooker and shred them using two forks.
Return the shredded chicken to the soup and stir well.
Add the lime juice to enhance the flavors before serving.
Serve hot, garnished with tortilla chips and any desired toppings like cilantro, avocado, cheese, or sour cream.
