Guy Fieri lays out what may be the hardest challenge in Flavortown history: Three chefs can only use 26 ingredients -- one for each letter of the alphabet -- over the course of two rounds. In round one, the chefs must make a chicken dinner using 13 ingredients, each one starting with a different letter from A to M. Then, round two has the remaining two chefs create their go-to seafood dish using 13 ingredients starting with letters N to Z. The chef with the highest score after this one-of-a-kind culinary spelling bee will get a shot at winning $20,000.

Guy Fieri welcomes four chefs who are thankful for their previous GGG wins back to compete in the toughest Thanksgiving competition ever: making both a Thanksgiving hors d'oeuvre and dinner in just one hour. First, each chef must serve up a family favorite hors d'oeuvre. Then, the competitors spin a wheel to determine what ingredient they'll have to incorporate into their Thanksgiving dinner. The winning chef will end up stuffing their wallet with up to $20,000.
