Heat a Dutch oven or large pot over medium heat and add the ground beef. Break the beef into crumbles as it cooks. Once the beef is slightly pink add in the onion, red bell pepper, and minced garlic. Saute for 3-4 minutes.
Drain any grease from the ground beef.
Add the taco seasoning and stir to combine.
Pour in the beef both, enchilada sauce, fire roasted tomatoes, corn, and black beans. Bring the mixture to a boil, reduce the heat and simmer for 20 minutes.
Let the soup cool slightly before serving.
