This type of roll was popularized by Italian American immigrants, who filled them with Italian-style cured meats, cheese and pickled vegetable antipasti (like giardinera). The original “Italian” sub inspired many variations that are now famous in their own right, like the Philly Cheesesteak (recipe below!). These rolls contain just enough oil and sugar to make the crust thinner and softer than a baguette or other “straight’ dough (dough without sugar or oil), but not as soft as a hamburger bun or sandwich loaf. They freeze well, so go ahead and make big batch to keep on hand for when you need a quick sandwich fix
