What is "hoagie"?

A hoagie is a type of sandwich that is made on a long, cylindrical roll, typically made from Italian or French bread. The roll is sliced lengthwise and filled with a variety of meats, cheeses, vegetables, and condiments, such as lettuce, tomato, onion, mayonnaise, mustard, and oil and vinegar dressing. Hoagies are similar to subs and are often used interchangeably, although some people may consider hoagies to be a regional variation of the sub. Common meats used for a hoagie include ham, turkey, roast beef, salami, and chicken, while cheeses can range from provolone to American. The sandwich is often served cold, but can also be heated in an oven or on a griddle to melt the cheese and warm the meat. Hoagies are a popular food item in many regions of the United States, particularly in the Northeast and Mid-Atlantic, and are available at delis, sandwich shops, and fast food restaurants.
