Submarine sandwich (sub)
A submarine sandwich, often called a 'sub,' is a long, hearty sandwich served on a baguette-style roll and typically filled with layers of deli meats, cheeses, lettuce, tomatoes, onions, and a variety of condiments. It originated in Italian-American communities in the northeastern United States during the early 20th century, with regional names like 'hoagie,' 'hero,' or 'grinder' reflecting local traditions.
🍽️ Nutrition at a glance
A typical sub is high in carbohydrates from the bread and can be high in fat depending on the meats, cheeses, and sauces used, though it also provides a good amount of protein from the fillings. A standard 6- to 8-inch sub generally ranges from 400 to 800 calories, with significant contributions from sodium and fiber if loaded with vegetables.
