In a large pot, combine the chicken, black beans, pinto beans, diced tomatoes, corn, enchilada sauce, chicken broth, taco seasoning, cumin, chili powder, and garlic powder.
Bring the mixture to a boil over medium-high heat.
Lower the heat and let the soup simmer for 20-25 minutes, stirring occasionally.
Top with shredded cheddar cheese, sour cream, jalapeños, and cilantro if desired.
