This is a slight change from the original pesto. Lemon zest keeps it lively. Pistachio's keeps it a little cheaper then pine nuts. If you don't like cilantro use all basil. I myself love cilantro. Serve over hot pasta, dollop of pesto in vegetable or chicken soup, use pesto instead of your favorite spread on your sandwich, top a pizza with it and spread some on salmon or chicken then bake.
- Put all of the ingredients in the food processor or blender and puree until smooth.
- Start with 1/4 cup oil adding more if you need.
