The term "Earl of Sandwich" refers to a title in the British nobility, created in 1660. The most famous holder of this title was John Montagu, the 4th Earl of Sandwich, who is often credited with inventing the sandwich. He reportedly ordered his meat served between two slices of bread so he could eat while continuing to play cards. The sandwich has since become a popular food item worldwide, enjoyed in various forms and fillings. It typically consists of ingredients like meats, cheeses, vegetables, and spreads placed between slices of bread, making it a convenient meal option for many.
