Nothing says summer like a good old-fashioned barbecue on the beach. Giada De Laurentiis and her weekend guests cook up a feast made almost entirely on the outdoor grill. The seasonal surf and turf menu features Grilled Plum Salad, Spicy Melon Salad, Grilled Skirt Steak with Smoky Herb Sauce and Grilled Halibut with Olive Bagna Cauda.
