Since 1867. Italian recipe. Produced in Liguria, Italy, the original home of Pesto, this Genovese classic is bursting with the flavor and aroma of fresh basil. Adding Filippo Berio olive oils to the recipe takes the flavor even further. Pesto perks up pastas and pasta salads, potato salads, sandwiches and soups. And it's a surprisingly scrumptious ingredient in hummus and dips! Non-vegetarian cheese.
