Pesto is a luscious, herby and garlicky sauce traditional to Northern Italy. It’s usual constituents are basil, garlic, olive oil, pine nuts, and grated cheese. Since I don’t eat dairy, I skip the cheese and I still tastes great. You could throw in some nutritional yeast to lend a bit of cheesy flavor if you like.
One reason I wanted to make pesto is because I wanted to use my new (used) food processor. It worked great!
