Brown 1/2 pound ground beef in bottom of a big soup pot. Add the following cans (dump the whole can, including any accompanying liquid): 1 can corn, 1 can red kidney beans, 1 can diced tomatoes, 1 can tomato sauce. Then add 1/2 package of taco seasoning. Heat until warm.
You can garnish it with cheddar cheese and sour cream and can add whatever other toppings you like to it. Serve with tortilla chips which can be crushed and put on top of the bowl of soup, or you can use them to dip into the soup and eat.
We also recently tried this using some grilled and cut up chicken and it was very good as well. Enjoy!
