Ree Drummond is upping her potluck game with four fabulous portable ideas for barbecue season. Her 8-Layer Dip takes snacking to the next level with its grown-up flavors. Then there's an awesome salad duo -- BBQ Potato Salad that turns a classic into a buffet must-have and Blueberry Cornbread Panzanella that's certain to be the star of any spread. Ree has desserts covered, too, with a refreshing Lemon Icebox Pie that's a sweet ending for any get-together.
