Add Rotel tomatoes, black beans, corn, onion, bell pepper, garlic, chicken broth, taco seasoning, cumin, chili powder, salt and pepper to slow cooker. Stir to combine.
Cover and cook on LOW 7-8 hours or HIGH 3-4 hours.
Remove chicken and shred with two forks. Return shredded chicken to slow cooker.
Stir in lime juice.
Taste and adjust seasoning as needed.

Notes
Pro Tip:
Don't add the lime juice until the very end - cooking it for hours will make it bitter. Fresh lime juice at the end is what takes this from good to incredible.
