Nothing says summer like a patio party, so Valerie Bertinelli is hosting a "beginning of summer" get-together with her husband, Tom, and their best friends. The seasonal party menu includes Grilled Vegetables with Avocado Yogurt Dip, Tapenade Aioli Dip, Grilled Shrimp Salsa, Skirt Steak with Chermoula and a Hibiscus and Lavender Prosecco Punch to toast in the new season.
