Rach's Sheet Pan Sausage & Pesto Pasta + Tuna Summer Rolls

Rachael's kicking off the show with a sheet pan sausage dish with grapes that's packed with flavor and a pesto pasta dish made with farro spaghetti. Then, "Top Chef's" Chef Tu David Phu is making summer rolls as we head into warmer weather, and food writer Rick Martinez is throwing down guajillo chicken tostadas—and it's epic. Meanwhile, chef and restaurateur Katsuji Tanabe is making his chicken enchiladas.
