Sandwich is a kind of food, usually consisting of vegetables, cheese slices or meat, placed on or between bread slices, or more generally, any dish that uses bread as a container or wrapping paper for another food type. Sandwich was originally a portable and convenient snack in the western world, but with the passage of time, it began to become popular all over the world.

The definition of sandwich varies with national English varieties. In American English, the word is widely used, including any stuffing between two pieces of bread, while British English (and some other English varieties, such as Australia) has a narrower definition of sandwich, which requires cutting bread from bread, and other words are used for other forms of bread with stuffing (such as rolls).

Sandwich is a very popular lunch food, which is used as a part of take-away lunch at work, school or picnic. Bread can be plain or coated with mayonnaise or mustard to enhance flavor and texture. In addition to homemade sandwiches, they are widely sold in various retail stores, and can be eaten both hot and cold. ? There are salty sandwiches such as cooked meat sandwiches and sweet sandwiches such as peanut butter and jelly sandwiches.
