A club sandwich, also called a clubhouse sandwich, is a sandwich of bread (occasionally toasted), sliced cooked poultry, fried bacon, lettuce, tomato, and mayonnaise.[1][2][3] 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 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. Other sources, however, find the origin of the club sandwich to be up for debate. Another theory is that the club sandwich was invented in an exclusive Saratoga Springs, New York gambling club in the late 19th century. The sandwich is commonly served with an accompaniment of either coleslaw, or potato salad, and often garnished with a pickle. The coleslaw or potato salad is often reduced to a "garnish" portion, when the primary accompaniment is an order of french fries or potato chips.
