How many days is the shelf life of Starbucks sandwiches?

In all western recipes, any kind of bread or rolls, any kind of convenient food, can be made into sandwiches. In the United States, the "hot sandwich" with steamed stuffed bun and beef is the most common nutritious fast food; Peanut butter and jelly sandwiches are the main foods for primary school students.

The "nightclub sandwich" made of chicken or turkey slices, bacon, lettuce and tomatoes, and the "capital sandwich" made of salted beef, Swiss buttermilk and kimchi baked with Russian toppings are more expensive, and are mainly sold in high-end restaurants and dance halls.

The history of sandwich is almost as long as cake, but it doesn't seem to have a specific name at first. There is another 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.
