The Kitchen is honoring Earth Day with fresh finds for spring. Geoffrey Zakarian makes a Peruvian Seafood Stew with Cilantro Broth, and then Jeff Mauro goes green with his Italian Stuffed Artichokes. Cookbook author Lindsay-Jean Hard shares the secret to her stem-to-peel Banana Peel Cake, and Katie Lee takes on Meatless Monday with Asian-Style Eggplant "Meat"balls. Jeff and Katie go head-to-head in a competition using broccoli stalks for a special guest judge, Food Network's Valerie Bertinelli. Finally, the hosts give some sustainable snacks a taste test.
