Grannys Frito Salad

Preparation : The best way to make this salad is in a glass bowl. Layer each ingredient in order given: onions, tomatoes, lettuce. Sprinkle beans over. Shake dressing, pour over entire salad. Let set for 3 hr. or so. DO NOT STIR IT AT ALL. When you get ready to eat, give the Frito bag to the kids and let them crush the chips in the bag. Or, take out your aggression by placing the bag in the driveway and running the car over it a couple times. However you do it, spread the chips over top. Let folks dig down in for all the goodies. You don't need to worry about refrigerating it at the time, which makes this great for picnics. Do store the leftovers, covered, in the refrigerator (if there are any).
