Egg salad sandwich is a simple and humble American sandwich dating back to sometime in the 1800s, but not before 1762 because that's when the sandwich was formally invented. It consists of a combination of peeled hard-boiled eggs, mayonnaise, salt, and pepper between two slices of bread.

Before the egg salad was placed between bread, in the early 1900s, it used to be served on a bed of lettuce. Nowadays, it's an American staple because it's so simple and everyone has the basic ingredients to make the egg salad sandwich in their kitchen.
