But you can easily make fresh pesto in the fall or winter using parsley and walnuts instead of basil or pine nuts. It’s just as green, garlicky, cheesy, and nutty. And great on pasta, with beef, or as a sandwich spread. I’ll even put it in cheese tacos. Or just keep dipping my fingers in until it’s all gone. Oops! Use immediately or cover with plastic wrap and refrigerate to store. Will last several days chilled. Use with pasta or as a spread on bread or toast.
