A club sandwich, also called a clubhouse sandwich or double-decker, is a sandwich with two layers of fillings between 3 slices of bread. It is often cut into quarters and held together by cocktail sticks. To order a club sandwich without the third piece of bread you would ask the waiter to "hold the club".

The traditional club ingredients are turkey on the bottom layer, and bacon, lettuce, and tomato on the top (it is sometimes called the "turkey club"). Other club sandwich variations generally vary the bottom layer, for example a "chicken club" or a "roast beef club." As with a BLT sandwich, the club sandwich is usually served on toasted bread, but untoasted bread can be used. Mayonnaise is a common condiment, but honey mustard is sometimes used. Some versions also contain ham. Cheese is often added to the sandwich as well, usually Swiss, American, or Cheddar.

This, my friends, is a sandwich...
