This Basil Spinach Pesto Recipe is my all time favorite pesto. It's adapted from the wonderful author and syndicated columnist Diane Rossen Worthington’s recipe in her cookbook, A Taste of Summer. In addition to being bright, bold and full of flavor, this sauce is also super versatile - serve it on pasta, pizza, with our Smoked Salmon Chopped Salad, or as a flavor enhancer in appetizers.
