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.

It's holiday time on Chopped! The competitors are challenged to stay in the spirit of the season throughout the meal. In the appetizer round the chefs, not-so-gingerly, take down some gingerbread houses. And adrenaline runs so high that one chef does not realize that something has gone very wrong with his dish until it is too late. Then, in the entree round, a prized piece of meat and a beautiful vegetable have the makings of a great main dish, but a sweet surprise in the basket may present "ye old yuletide" pitfall for the chefs. And when the finalists find an often-disparaged holiday classic in the dessert basket, who will be able to elevate the ingredient and be on their merry way with $10,000?
