National Sandwich Day is celebrated on November 3rd each year. This day honors the popular food item known as the sandwich, which consists of various fillings placed between two slices of bread. The sandwich is believed to have been named after the 4th Earl of Sandwich, John Montagu, who is said to have ordered his meat served between bread to avoid interrupting his gambling. On National Sandwich Day, many restaurants and delis offer special deals and promotions on sandwiches. People often take the opportunity to enjoy their favorite types of sandwiches, whether it's a classic ham and cheese, a BLT, or a veggie option.
