Pesto is one of the most popular pasta toppings in Italy. It originated in Liguria, specifically in Genoa. This flavorful sauce is made of basil, extra-virgin olive oil, parmesan cheese, pecorino cheese, pine nuts, garlic and salt, traditionally ground in a ceramic or marble mortar. Use it on pasta, as a spread for sandwiches, paninis and crostini toast appetizers. Drizzle on caprese salads of fresh basil, cherry tomatoes and fresh mozzarella. Bake up a pesto pizza or a colorful Italian-inspired flatbread. Finish grilled meats and seafood, roasted vegetables and breakfast eggs.
