Recipe(tried): This one has 6 layers

1. Frito Lay Bean Dip
2. Mix together 1/2 cup mayo, 1 cup sour cream, 1/2 package taco seasoning mix
3. Green onions (cleaned and finely sliced)
4. Sliced ripe black olives
5. Three tomatos (remove seeds and chop/dice)
6. 1/2 lb medium cheddar cheese

Layer in order (1 at bottom, 6 at top). I think at one time there were seven layers to this (with avocado once #2--I've always made it this way cuz I am allergic to avocado). You can add a whole package of taco seasoning if people like stuff really spicy.
