Food Network's Bev Weidner thrills on the grill with her Grilled Salmon Tacos, and Chef Robert Irvine brings his Peach BBQ Chicken with Cucumber and Tomato Salad. Geoffrey Zakarian makes his spin on a classic, Grilled Pineapple Upside Down Cake, and the hosts usher in summer with stepped-up s'mores.
