Preheat dutch oven or stockpot on camping stove.
Brown ground beef (or turkey / chicken) in dutch oven, stirring frequently to break up large pieces. NOTE: You can also brown and drain the ground meat prior to camping. Store it in a ziplock bag in the fridge or cooler for up to three days before using.
Add the minced onion, taco seasoning, tomato sauce, diced tomatoes, corn, and kidney beans (including the liquid from the canned tomatoes, corn, and kidney beans) to the dutch oven with the cooked meat. Mix well to combine all ingredients.
Place the lid on the dutch oven or stockpot and simmer for 15 minutes, stirring occasionally.
Serve in bowls. Top with shredded cheese and sour cream. Perfect for scooping up with Fritos Scoops chips!
