Every year on November 3rd, National Sandwich Day is celebrated, honoring one of the world's earliest convenience foods. The sandwich stands out as one of the most widely consumed foods globally. This day coincides with the birthday of John Montagu, a British aristocrat also known as the Earl of Sandwich, who was connected to the UK's royal family.

Legend has it that during an 18th-century, 24-hour gambling session, Montagu requested a one-handed meal from his servants. In response, his cook placed some meat between two slices of bread, giving birth to the iconic sandwich. Intriguingly, the town of Sandwich is situated next to another town named Ham.
