Guy Fieri pulls no punches when he challenges All-Star chefs Madison Cowan, Elizabeth Falkner, Aaron McCargo Jr., and Michael Psilakis to make an upscale dinner using the double whammy of frozen and canned foods! Next, it's time for multiple cart swaps in a weekend brunch edition of Musical Carts! Then, the remaining two All-Stars must turn a kernel of an idea into their best dish using corn two different ways, with ingredients from three aisles. Our winning All-Star shops for up to $20,000 for their charity.
