Going to the grocery store could be worth $20,000 for one chef in each episode of this competition series. Four chefs compete in three elimination challenges testing their culinary skills as they make their way through the store's aisles. Each challenge features a theme -- such as using only items from frozen foods -- and is judged by a rotating list of guest judges who determine which contestant is eliminated. The chef who makes it through all three challenges then has two minutes to go through the aisles collecting items on a shopping list. Each item on the list is worth $2,000 and if the chef gets every item, the $20,000 grand prize is awarded. Popular Food Network personality Guy Fieri hosts the competition.
