Pesto is an Italian word meaning to pound or crush, traditionally made in a mortar (stone bowl) with a pestle (wooden mallet). Usually pesto is made with basil, pine nuts, parmesan cheese, garlic, and olive oil. But, it can also be made with any herb or green leafy vegetable and different nuts. Suggestions are: parsley and walnuts, cilantro and pistachio nuts, coriander and hazelnuts, sage and walnuts, and try some shredded kale or arugula, walnuts and parmesan cheese! Puree any combination in a mini food processor with a handful of shredded hard cheese, 1 garlic clove, salt, and enough olive oil to make a paste. Toss with your favorite hot pasta! Enjoy new tastes!
