Class is in session in the Chopped kitchen! Four school cafeteria chefs compete to raise awareness about the importance of good meals for kids. With White House chef Sam Kass as a guest judge, the ladies seek to make a big impression with their first dishes, made with dill pickles and canned tuna. Then in the entrée round, quinoa is a new ingredient for two out of the three chefs. Will they be able to take something unknown and create something great? The two finalists pour their hearts into making fantastic desserts that include grapes and cream cheese. And an emotional victory brings an incredible competition to its conclusion.
