Grilled Watermelon Steaks with Walnut Gremolata

Welcome to the grill, watermelon. Marinate these thick-cut “steak” fruit slices in a mixture of white balsamic vinegar, lemon juice and rosemary. Grill watermelon slices and top ‘em with a gremolata of walnuts, lemon zest and fresh parsley for knock-the-grill-tongs-out-of-your-hand taste.
