Mixed Grill of Summer Squash and Zucchini with Pesto

Instructions

• Make the pesto: In a small food processor or blender process the basil, garlic, pine nuts, and ½ teaspoon salt. Then, with the motor running, drizzle ¼ cup oil through the feed tube until the mixture forms a thin paste, scraping the sides of bowl if necessary. Add the cheese and process briefly, just until combined. Set aside until ready to use; or transfer to a jar with a tight-fitting lid and refrigerate for up to 3 days. Bring to room temperature before serving.
