Panino con mortadella

Panino con mortadella is an Italian sandwich that has mortadella as its main ingredient. There is no set recipe, and there are many variations. The bread can be any kind of bread, but most often, you will see rosetta, a bulbous, slightly hollow bread perfect for holding the filling, focaccia, and ciabatta, or, if in Rome, pizza bianca.

As far as filling, as stated earlier, it can be a mortadella-only filling, but it will usually have additional ingredients, typically some kind of sauce, cheese, and vegetables.
