Chefs from four distinct American regions vie for culinary supremacy. First up, turning a hometown hit into a homerun when you only get five ingredients. Next, it's sink or swim when chefs make a seafood supper using nothing but frozen food. Then, how do you prepare one protein two different ways when you can only use items from three aisles? The winning chef wins bragging rights for his region plus big bucks in the Shopping Spree worth up to $20,000.
