This is a complete pasta meal kit from the Italian brand Pastarotti. It includes dry spaghetti pasta and a separate packet of dry pesto sauce mix. The sauce mix typically contains dried basil, garlic powder, Parmesan cheese powder, pine nut or cashew powder, salt, and sometimes olive oil powder. When rehydrated with water and/or oil, it creates a fresh, herbal, and nutty pesto sauce to coat the spaghetti for a quick, classic Genovese-style dish.
