1. The earliest origin of the sandwich can be traced back to the Jewish Hillel the Elder. It is said that in the 1st century BC, he had already sandwiched lamb and herbs in Jewish bread and enjoyed it on Passover. This is the earliest and most sandwich-like way of eating recorded in historical records. At that time, the word "sandwich" had not yet been invented.

2. Another interesting record about sandwiches in history is that in the Middle Ages, nobles would use rotten bread as plates to hold some food. After the meal, these "bread plates" soaked in food would be distributed to beggars or dogs. Of course, the nobles could also eat them themselves. These "bread plates" can be said to be an early prototype of the "open sandwich".

3. Sandwich was first recorded as a noun in an article written by historian Edward Gibbon in the 18th century. In an article, Edward Gibbon called "small pieces of cold meat" "sandwiches" (yes, there was a time when people referred to "sandwiches" as referring to the meat sandwiched between them). This name actually originated from Since John Montague, an English Earl in the 18th century.

4. John Montague is the Fourth Earl of Sandwich. It is said that this Earl especially likes to play cards, playing to the point of forgetting to sleep and eat. His servant had to put meat, cheese and vegetables in bread so that he could fill his stomach while playing cards without soiling the cards with his hands that touched the food.

5. The earl got into the mood while playing cards, so he named this food the name of his title: Sandwich.

6. Therefore, in the 18th century, sandwiches were mostly regarded as shared food during night gambling and entertainment. Later, they became a late-night snack for the nobles.

7. In the 19th century, with the development of industrial society, sandwiches became a popular food for workers in the United Kingdom and Spain because they were portable, convenient, filling, and very suitable for eating when going out to work.

8. In the 20th century, bread became a typical representative of American diet, and sandwiches, which took advantage of this trend, began to become popular around the world. In the American TV series "Chef", the flower-armed chef Jon Favreau started a business in a mobile food truck.
