Brown the ground beef in a saute pan; drain. Add about 1/3 of the taco seasoning packet to the beef and mix.
In a large pot, combine remaining taco seasoning, diced tomatoes, black beans, whole kernel corn, and chopped green chilies. Liquid and all!
Add the ground beef to the pot mixture and stir well. To serve, add chips to the bottom of bowls and pour soup over them. Sprinkle cheese over the soup and enjoy!
