Meatball sandwich

The meatball sandwich is a popular dish in Italian-American cuisine, consisting primarily of meatballs (typically made from beef or pork), tomato sauce (commonly marinara), and bread such as Italian bread, baguette, or bread rolls. Cheese varieties like provolone and mozzarella are often included, and additional ingredients may encompass garlic, green pepper, and butter. This sandwich is sometimes prepared in the form of a submarine sandwich. The exact origin of the meatball sandwich in the United States is disputed, with suggestions that it was invented around the turn of the 20th century. (en.wikipedia.org)
