The history of sandwich is almost as long as cake, but it doesn't seem to have a specific name at first. There is an interesting story about the origin of sandwiches.
Sandwich was originally an unknown town in southeast England. There is a sandwich count named John montague in town. He is a card lover. He is addicted to card games all day and forgets to eat and sleep. It was difficult for the servant to serve his diet, so he put some vegetables, eggs and sausages between two pieces of bread and let him eat while playing cards.
Unexpectedly, montague was overjoyed to see this kind of food and casually called it "sandwich". When he was hungry, he shouted, "bring sandwiches!" " Other gamblers followed suit and began to eat sandwiches while playing cards. Soon, sandwiches spread all over the British Isles, to the European continent, and later to the United States.
