Guy Fieri brings three GGG winners back to compete against each other for a chance to go up against GGG's most feared competitor and judge, Iron Chef Alex Guarnaschelli. First, Guy picks a letter at random that each ingredient in their first dish must start with. Then, the chefs are tasked with making an international classic without shopping in some key aisles. The lone chef left standing wins an automatic $10,000 and gets to face Iron Chef Guarnaschelli for another $10,000.

Five masters of their own protein -- beef, chicken, pork, seafood and veggies -- collide in a battle for protein supremacy. Right off the bat, Guy Fieri gives them 20 minutes to make something between buns, and then they get a helping hand with a list of ingredients to use in a regional dish. The chefs in the final round get only eight ingredients to make their dinner dishes, and one protein master will best the others and win a guaranteed $20,000.
