Club sandwich

A club sandwich, also called a clubhouse sandwich, is a sandwich consisting of bread , sliced cooked poultry, fried bacon, lettuce, tomato, and mayonnaise. It is often cut into quarters or halves and held together by cocktail sticks. Modern versions frequently have two layers which are separated by an additional slice of bread. The club sandwich may have originated at the Union Club of New York City. The earliest known reference to the sandwich, an article that appeared in The Evening World on November 18, 1889, is also an early recipe: "Have you tried a Union Club sandwich yet? Two toasted pieces of Graham bread, with a layer of turkey or chicken and ham between them, served warm." Several other early references also credit the chef of the Union Club with creating the sandwich.
