Panino
A panino (plural panini, although panini is often used in a singular sense outside Italy) is a toasted sandwich made from a small loaf of bread, typically ciabatta. The loaf is often cut horizontally and filled with salami, ham, meat, cheese or other food, and served hot.
"Panini" is also a brand of grill made specifically for grilling these sandwiches.
In Italian, panino can variously refer to a bread roll or a sandwich.
