Regional Note: The long sandwich featuring layers of meat and cheese on a crusty Italian roll or French bread goes by a variety of names. These names are not distributed in a pattern similar to that of other regional words because their use depends on the business and marketing enterprise of the people who create the sandwiches and sell them. Submarine and sub are widespread terms, not assignable to any particular region. Many of the localized terms are clustered in the northeast United States, where the greatest numbers of Italian Americans live. In Maine, it is called an Italian sandwich, befitting its heritage. Elsewhere in New England and in Sacramento, California, it is often called a grinder. New York City knows it as a hero. In the Delaware Valley, including Philadelphia and southern New Jersey, the sandwich is called a hoagie. Speakers in Miami use the name Cuban sandwich. Along the Gulf Coast the same sandwich is often called a poor boy. In New Orleans, a poor boy is likely to be offered in a version featuring fried oysters.
