History of the sub

The sandwich originated in several different Italian American communities in the Northeastern United States from the late 19th to mid 20th centuries. Portland, Maine claims to be the birthplace of the Italian sandwich and it is considered Maine's signature sandwich. The popularity of this Italian-American cuisine has grown from its origins in Connecticut, Pennsylvania, Delaware, New York, New Jersey, and Massachusetts to most parts of the United States, and with the advent of chain restaurants, is now available in many parts of the world. In Europe it would simply be known as a baguette, or a ciabatta, named after traditional breads long baked in France and Italy.
