This is my mom's recipe and has been a family favorite for ages. I've seen other recipes out there, but here is a QUICK version that doesn't require too many ingredients or prep.
1 lb. ground beef, browned and drained
1 envelope taco seasoning
1 envelope ranch seasoning
1 can Rotel (tomatoes and chilis)--mild is recommended
1 can corn (I even use cream corn and it works great!)
1-2 cans of beans (I use 1 can of pinto beans)
3-4 cups of water, depending on your taste
Combine all together and heat on the stove until hot. Serve with sour cream, cheese, and tortilla chips. I can't tell you how delicious this soup is!
