Three of GGG's favorite all-star chefs team up with a teacher who has made a difference in their lives in order to thank them for all they've done. First, Guy Fieri has these teacher/chef duos make an elevated kid's dinner using only the ingredients they can fit inside a lunchbox, including the classic lunch snacks already packed! Then, the teams must make a teacher appreciation dinner on a $15 budget, plus whatever extra money they can win answering pop quiz questions. The top of the class will earn their teacher the ultimate thank-you gift -- up to $20,000 in cash!
