In many English-speaking countries, a panino (Italian pronunciation: [paˈniːno], from Italian, meaning "small bread, bread roll") is a grilled sandwich made from bread other than sliced bread. Examples of bread types used for panini are baguette, ciabatta, and michetta. The bread is cut horizontally and filled with deli ingredients such as cheese, ham, mortadella, salami, or other food, and often served warm after having been pressed by a warming grill. There is widespread availability and use of sandwich presses, often known as "panini presses" or "toasted sandwich makers".
