World Sandwich Day celebrates one of the world’s most adaptable foods

The sandwich is one of the most familiar and versatile foods, suitable for breakfast, a quick lunch, a snack or an easy dinner. It can be served cold or hot and made with many types of bread and fillings, from ham and cheese to tuna, omelette, vegetables, chicken and different sauces.

The name is traditionally linked to John Montagu, an English aristocrat whose title became associated with eating meat between slices of bread. The idea spread internationally and has since developed into countless regional and personal variations.
