Stir in taco seasoning, corn, black beans, tomatoes, tomato sauce, and green chilis. Simmer on low heat for 20 to 30 minutes.
Serve with tortilla chips and your favorite toppings.
This makes an easy freezer meal too! After cooking, let soup cool down and then dump into a gallon-sized Ziploc bag or other freezer container. When you want to eat it, let it thaw in the fridge for 24 hours and then simmer on the stove until heated all the way through or microwave until heated all the way through.
You could also put this soup in your crock pot and cook on low for 2-3 hours or until heated through.
