Pesto

is a sauce that originates in the city of Genoa in the Liguria region of northern Italy (pesto alla genovese). It can be used as a sauce for pasta or meat, or can be used as an ingredient in a variety of dishes. One classic use is to spread the pesto onto slices of bread which are then toasted. The word "pesto" derives from the Italian for pestle, pestello.
