Brown ground beef and drain.
Add the amount of taco seasoning for the amount of cooked beef.
Add pinto beans, black beans, and enough sour cream to make it paste-like. It won’t look very appetizing, but trust me, it’s good!
Put some crushed tortilla chips in the bottom of casserole dish, layer half the meat mixture and top with some shredded cheese. Repeat layers, ending with cheese on top.
Bake at 350° until heated through and cheese is melted.
Can serve with lettuce, tomato, salsa, avocados, guacamole, whatever! You can also add green chili's or peppers, it’s pretty versatile and I just used what I had on hand.
