A sandwich is a food item consisting of one or more types of food 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 some other food.[1][2][3] The sandwich was originally a portable food item or finger food which began its popularity in the Western World. Today sandwiches in various versions are found worldwide.
Sandwiches are a popular type of lunch food, taken to work, school, or picnics to be eaten as part of a packed lunch. The bread can be used plain, or it can be coated with one or more condiments to enhance the flavours and texture. As well as being homemade, sandwiches are also widely sold in restaurants and cafes, and are sometimes served hot as well as cold.
