With summer ending and shorter days ahead, Valerie Bertinelli throws one last backyard soiree with her friends and family -husband Tom, chef Stuart O'Keeffe, actress Mackenzie Phillips, and Larry and Angela Robinson. She prepares an all-grilled menu: Salmon Burgers, Avocado and Grilled Corn Salad with Goddess Dressing, Grilled Sweet Potato Wedges and even a Grilled Pound Cake with Grilled Peaches, served with a Cinnamon Simple Syrup.
