It's all about summer celebrations in Ree Drummond's ranch kitchen. She starts by making easy, customizable Roasted Brisket Sliders and a Big Grilled Veggie Salad, which is an ideal party side dish. Then there's a stunningly simple Lemon and Berry Icebox Cake and fizzy, fabulous Sparkling Sangria. It's summertime, and Ree is celebrating!
