Cilantro, Pistachio, Almond And Castelvetrano Sauce

This sauce has a nice balance of flavors. I like it with corn chips or tacos, roasted potatoes, rice and beans or grilled vegetables. Castelvetrano olives are pretty, bright-green olives, juicy and mild with a vegetal flavor. You can substitute other green olives, but the flavor and color won't be quite as bright.
