A sandwich is a food typically consisting of vegetables, sliced cheese or meat, placed on or between slices of bread, or more generally any dish wherein two or more pieces of bread serve as a container or wrapper for another food type. The sandwich began as a portable finger food in the Western world, though over time it has become prevalent worldwide.

Sandwiches are a popular type of lunch food, taken to work, school, or picnics to be eaten as part of a packed lunch.
