The tramezzino is a usually triangular sandwich constructed from two slices of soft white bread with the crusts removed. Tramezzini are popular and inexpensive snack sandwiches available at many Italian bars throughout the day. Popular fillings include tuna and olive and prosciutto, but many other fillings can be used. The origin of the tramezzino can be found in the Caffè Mulassano di Piazza Castello in Turin where it was devised in 1925 as an alternative to English tea sandwiches. Today the bar offers 40 varieties of tramezzini. The word tramezzino was invented by Gabriele D'Annunzio as a replacement for the English word "sandwich", being easier to pronounce and a completely Italian term (albeit a neologism). "Tramezzino" sounds like "in-between", with the addition of the diminutive suffix "-ino". The Tramezzino sandwich would never have been born if the Nebbiolo family had not put in their luggages what in Italy at that time was a "futuristic" tool: the toaster. Angela and Onorino, owners of Coffee Mulassano, decided not only to toast the bread in it, but also stuff that bread with sauces, meats, salad and whatever else could be popular for their clients. According to the story the first filling for the Tramezino sandwich was made out of butter and anchovies.
