Add the chicken thighs to the bottom of your slow cooker.
Top with the chili powder, sea salt, cumin, and black pepper.
Dice the onion and pepper and add to the slow cooker.
Then, add the tomatoes, corn, black beans and broth.
Cook for 4 hours on high (or 8 hours on low) and then remove the chicken and shred with two forks. This will be easy because the chicken gets so tender.
Taste the broth to see if it needs more salt, stir in the chicken and remove from the heat.
To serve, in each bowl put about 1/2 cup of crushed tortilla chips and spoon the soup over top. Finish with Greek yogurt or sour cream, cilantro, scallions, avocado – or whatever you want!
