Grinder vs. Submarine — What's the Difference?

Grinder refers to a type of sandwich that is particularly popular in the Northeastern United States, especially in New England. This term typically describes a long sandwich made on a split roll filled with various meats, cheeses, vegetables, and condiments. Submarine, often shortened to "sub," is a more widely recognized term across the United States. Like the grinder, a submarine is a long sandwich made on a split roll and filled with a variety of ingredients.

Grinders are especially associated with Italian-American cuisine and might include ingredients like salami, pepperoni, and provolone cheese. Submarines, while they can also feature Italian ingredients, are more generic and can encompass a wider range of fillings, from cold cuts to hot fillings like meatballs or chicken parmesan.

In New England, the term grinder is a staple of local sandwich shops and delis. On the other hand, the term submarine or sub is ubiquitous across the country, found in national chains and local eateries alike. Despite regional preferences for the term grinder, most people across the U.S. would understand and recognize a submarine sandwich.

Grinders may sometimes be served hot and are often associated with toasted or baked sandwiches. Submarines, however, are commonly served cold but can also be found hot, making the term more flexible and broad in its usage. Both types of sandwiches are customizable with a wide array of ingredients to suit individual tastes.
