As far as food is concerned, there are several similarities in the food tradition of Italy and Spain: we both use olive oil rather than butter, we both make large use of tomato sauce, onions and the aromatic herbs of the mediterranean basin. Some local products are also very smiliar such as the Spanish Jamon (Serrano and Iberico) and the Italian Prosciutto Crudo (Parma and San Daniele being the most popular, although an immense variety is available).
In the whole basin of the Mediterranean sea, rabbit is used in several dishes and in some cases it even represents the flagship recipe of the Country such as for Malta, where rabbit (fenek, in Maltese) is at the base of the local cuisine. Don't forget about the Spanish Paella, whose original recipe, born outside the city of Valencia in the area of the Albufera swamp, is made with rice and rabbit (no fish).
