What’s a Sub Sandwich?

[ad_1]

A submarine sandwich, sometimes called a sub sandwich or simply a sub, is a hearty sandwich made up of a variety of deli meats, sliced ​​cheeses, and toppings such as shredded lettuce and sliced ​​tomatoes. The ingredients are assembled on a long roll or baguette and finished with an oil and vinegar sauce. The similarity of the roll to a real military submarine gives this sandwich its name.

There are several theories about the origin of the submarine sandwich, from an Italian immigrant’s recollection of a raised submarine to a more popular offering from Boston, Massachusetts, for nearby naval personnel. In general, the shape of the specially cooked thick bun resembles the rounded tubular shape of a real submarine, although modern submarines do not always adhere to that standard.

Considering the number of meats, cheeses, and toppings available, a modern submarine sandwich could be anything from a simple ham and cheese sandwich to a Dagwood-style stuffed monstrosity. Most feature two or three cured meats, typically prosciutto, salami, and bologna, and a mild cheese such as provolone, americano, or mozzarella. A generous supply of shredded lettuce and thinly sliced ​​tomatoes give the sandwich some moisture, and a dash of oily vinaigrette adds a slightly acidic bite.

If the sandwich is created in an authentic Italian deli, it may contain spicier Italian deli meats such as salami, ham, and pepperoni. Olives, pickles, peppers, and other savory seasonings can also be added to make it more flavorful. Although the original submarine sandwiches were served cold, a modern one can be heated under the elements of the grill until the cheese is melted and the meat has been thoroughly heated.

There are subtle or not-so-subtle differences between various deli sandwiches, but the same basic submarine sandwich may be known as a hoagie, grinder, bomber, or hero in different regions of the United States.
