Four Food Network Star chefs take to the aisles to compete on behalf of their favorite charity. First, Guy tasks them with making a lunchtime favorite only using 5 Ingredients or Less. Then, the chefs are challenged to make a steakhouse dinner — on a budget. The two finalists compete in one of the most difficult games yet, One Ingredient Per Aisle, in which they pull out all the stops to make the best dish for a good cause.
