My Mothers Taco Salad

This is a recipe that I grew up on and I make it for my own children. I totally crave this! Thanks Mom for your wonderful recipe!

1 1/2 lb cooked hamburger, drained
1 onion, chopped
1 lb. grated cheese
2 cans drained kidney beans
1 c. Thousand Island Dressing
Dash of Chili Pepper
2 tomatoes, diced
3 c lettuce, chopped
1 pkg. Nacho Doritos

Cook the hamburger and onions together. Drain the grease off and let it cool. Sprinkle chili powder over. When meat is cool, add to it the cheese, kidney beans, and dressing. Stir together. In another bowl, put the lettuce and tomatoes. In another bowl, put the Doritos and crush. Let each person make their own salad the way they want it.
