Depression Crab Salad - cooking recipe

Ingredients

2 heads iceberg lettuce, shredded thin
1/2 cup yellow onion, diced (to taste)
8 ounces crab (can use imitation)
1 -2 cup mayonnaise
salt and pepper

Preparation

In large bowl add shredded lettuce in 1/4-inch strips the thiner the better, but not too thin.
Dice onion and add to bowl. You can use less or more onion, but it has to have onion. I often add more depending on the hotness of the onion.
Chop crab and add to bowl, sometimes I add more crab.
Rule that I generally use is for every head of lettuce, I use at least 4 oz (or more) of crab and 1/2 of an onion.
Add 1 cup mayonnaise to bowl toss, add rest of mayonnaise by 1/2 cup tossing well after each. You may not need it all depending on the size of your heads of lettuce.
Salt and pepper to taste. This requires a lot of pepper you should be able to see the little black dots.
Left over this is good it seems to marinate and become even better.
