This month, August, is National Panini Month.
Paninis refer to a type of toasted sandwich that originates in Italy. In the United Kingdom, United States and Canada the name refers to a specific type of pressed and toasted sandwich.
These sandwiches are made using a panini, a type of bread, which is then sliced open and filled. The sandwich is then toasted, and pressed flat, in a panini press.
Paninis can be made with a wide variety of fillings. Paninis are often bought in stores pre-made, but can be made at home with a panini press if you have one. Other devices can be used to achieve the same effect.
