Start by gathering all your ingredients. Chop the sweet yellow onion and red bell pepper, and rinse the black beans. This prep work will make the cooking process much smoother.
In the bottom of your crock pot, place the 3 lbs of boneless, skinless chicken breasts. Layer the chopped onion and red bell pepper on top.
Next, pour the drained black beans and whole kernel corn over the chicken and veggies.
Add the chopped green chiles, salt, cumin, and garlic powder to the crock pot. Make sure everything is evenly distributed.
Finally, squeeze the juice of one lime over the top of the mixture. This will add a beautiful brightness to the dish.
Cover the crock pot and set it to low for 6-8 hours or high for 3-4 hours. The chicken should be tender and easily shreddable.
Once cooked, shred the chicken right in the pot using two forks. Mix everything together and stir in the chopped cilantro. Your Crock Pot Southwest Chicken is now ready to be served!
