The Kitchen is serving up a perfect plate of summer's best flavors, like Katie Lee's Cornbread Panzanella and Geoffrey Zakarian's "P-L-T" Burger with Pancetta, Lettuce and Tomato. Corn gets two new toppings with Sunny Anderson's creamy and spicy "Boom Boom" Corn and Jeff Mauro's Crunchy Ranch Corn. Cookbook author Justin Chapple joins the gang to make his Olive Oil and Herb Crushed Potatoes, and Jeff puts his five-ingredient spin on Frozen Key Lime Pie. Finally, the hosts play a game of Onion Ring Toss and share some of Katie's Caramelized Vidalia Onion Dip.
