The classic club sandwich is a delicious combination of turkey, bacon, lettuce, tomato, and mayonnaise stacked between three slices of bread. However, there are a few other names that you could use to describe this scrumptious sandwich. In some regions, it is referred to as a "double-decker sandwich" because of its towering appearance. Alternatively, it may be called a "triple-decker" or a "triple-layer sandwich" due to the three slices of bread used. Another name for this sandwich is a "CLT" because of the prominent ingredients used - chicken, lettuce, and tomato. Regardless of the name, the club sandwich remains a classic and much-loved dish.
