Meatball sandwich is an Italian-American invention typically consisting of a long Italian-style roll filled with meatballs, red sauce, and mild cheeses such as mozzarella or provolone. It is believed that this sandwich was invented in the USA at the turn of the 20th century.
"Take delicate, intensely lamb-y little meatballs, plop 'em on buns with a pleasingly meaty-tasting tomato sauce, and add creamy Caprino, an Italian goat's milk cheese: you've got our favorite meatball sliders in town."
"At first, the sandwich exhibits nothing out of the ordinary. The tomato sauce, simple and summery, just seems to have been made by a good cook. The mozzarella and torn leaves of basil are fresh.The meat is juicy and rosy pink on the inside, the color of a perfectly cooked pork chop. It is completely faithful to your memories while being much, much better than you remembered."
"These restaurants serve the best meatballs in America - These giant meatballs are then baked, sliced in half, and simmered in fresh-made marinara sauce all day long. This mom and pop meatball shop serves some killer meatballs."
"The meatballs are fluffy, specked faintly with fennel seeds, and made from an appropriate balance of beef and pork. Soaked in a bright marinara, they manage to lift the sandwich up, rather than bog it down to sloth-in-a-tar-pit territory, like many other versions you'll encounter. Here the bread's interior can soak up all the bright, tangy sauce, while the golden-brown crust will maintain its shape, and, with it, the integrity of the sandwich."
