Submarine Sandwich

Submarine sandwich consists of a long, split bread roll, filled with numerous ingredients such as meats, cheeses, sauces, vegetables, and seasonings. Depending on the regional variety, the sandwich is called differently throughout the United States. In the Midwest and California, it's grinder, in New York and Northern New Jersey, it's hero, in Delaware, it's sub, and in Baltimore, South Jersey, and Philadelphia, it's called a hoagie. Around New Orleans, it's known as po'boy, and in Maine, it's Italian sandwich, even if it has nothing to do with Italy. However, the submarine sandwich originated in the Italian-American communities in the United States in the late 19th century, called a sub because it looked like a submarine. Today, submarine sandwiches are known worldwide due to the rise of large chain restaurants and the fast food industry.
