Place pinto beans, black beans, corn, tomatoes, chicken, enchilada sauce, green chiles and chicken broth in a large stock pot over medium-high.
Stir in taco seasoning, cumin, chili powder, garlic powder and onion powder, then add salt and pepper, if desired. Taste and adjust seasoning, if necessary.
Bring mixture to a boil, then reduce heat to low and let simmer for 20-30 minutes, or until desired thickness is reached.
Serve hot, garnished with sour cream, tortilla strips and avocado. Enjoy!
