Cook and drain hamburger, sit aside. Cut up, rinse, and drain lettuce. Dice onion, green pepper, and onion. Open and drain kidney beans. Add hamburger, lettuce, onion, green pepper and tomato together. Toss. Then crush the bag of Doritos into smaller pieces ( make sure the bag doesn't explode out of one end-do it gently). Add to other ingredients. Add cheese. Then add Catalina dressing to taste. It usually takes a tad bit less than the whole bottle. Do not add the Doritos, Dressing, or cheese until the last minute as they will get soggy. I usually mix the other ingredients together and than I add the other after I get to my destination or about 15 mins. before event

This is a crowd pleaser and I am requested to make this a lot in the summer.
