A lettuce sandwich is a wrap with lettuce substituted for the bread,[1] or a sandwich with a filling consisting primarily of lettuce. It should not be confused with other sandwiches that use lettuce as one of many ingredients, such as the BLT sandwich or the tomato and lettuce sandwich. The lettuce sandwich has a long history in both the United States and the United Kingdom. It has been used as a metaphor to represent things like mundanity, weakness and poverty. In more recent times, the lettuce sandwich, including lettuce hamburgers have symbolized diets including the keto diet.[2]
