Combine raw chicken, diced tomatoes with green chilies, diced tomatoes, corn, black beans, chicken broth, onion, jalapenos, garlic, cumin, chili powder, salt, and black pepper into a slow cooker and stir to mix well.
Cover and cook on low for 6-8 hours.
At the end of cooking time remove your chicken breasts to a cutting board or plate and shred with two forks. Return shredded chicken to the crock pot and stir.
*Notes: I put frozen chicken breasts in and just shred them at the end. The chicken is so tender and moist! You can also put in fresh chicken breasts either whole or cubed. I just love how nicely it shreds, rather than cubing it at the beginning.
Serve hot and top with tortilla strips and shredded cheese. You may also top with avocado, plain greek yogurt, cilantro, guacamole, etc.
