Sardenara
Sardenaira is a pizza dish from the Liguria region of Italy. It is very similar to the pissaladière of Provence, France. Although termed a pizza, some consider it more akin to a focaccia.
In the city of Sanremo in western Liguria, it is often garnished with salted sardines.
It is also known as sardinaira or pizza all'Andrea, after admiral Andrea Doria (1466-1560), whose favorite food was the dish: a slice of bread with olive oil, garlic, and salted anchovy.
The dish predates the better-known Neapolitan pizza. Since the dish was created before the Columbian Exchange, traditionalists do not add tomatoes.
