Egg salad is part of a tradition of salads involving protein mixed with seasonings in the form of herbs, spices, and other foods, and bound with mayonnaise. Its siblings include chicken salad, crab salad, ham salad, lobster salad, and tuna salad. Egg salad is often used as a sandwich filling, typically made of chopped hard-boiled eggs, mayonnaise, mustard, minced celery and onion, salt, black pepper, and paprika. It is also often used as a topping on green salad.
