Brown the meat: In a large pot, cook the ground beef and diced onion until thoroughly browned. You will want to drain any excess grease. Just to let you know, I used freeze-dried hamburger/ground beef (rehydrated).

Add seasonings: Stir in the taco seasoning until the meat is well coated.

Pour everything in: Add the tomatoes, corn, kidney beans, and diced tomatoes.

Simmer: Bring the soup to a boil, then reduce the heat and simmer for 15 minutes.

Taste and adjust: Add salt and pepper as needed, then ladle into bowls and pile on the toppings.
