There are not too many nations that can say their national dish has become an international phenomenon. Italy has two such dishes, pasta and of course pizza.
The word "pizza" is thought to have come from the Latin word pinsa, meaning flatbread (although there is much debate about the origin of the word). A legend suggests that Roman soldiers gained a taste for Jewish Matzoth while stationed in Roman occupied Palestine and developed a similar food after returning home.
The popular pizza Margherita owes its name to Italy's Queen Margherita who in 1889 visited the Pizzeria Brandi in Naples. The Pizzaioli (pizza maker) on duty that day, Rafaele Esposito created a pizza for the Queen that contained the three colors of the new Italian flag. The red of tomato, white of the mozzarella and fresh green basil was a hit with the Queen and the rest of the world.
