Three all-star judges -- Beau MacMillan, Aarti Sequeira and Justin Warner -- and their moms are ready to shop and cook their way to a $20,000 victory for charity. First, Guy Fieri's mom gives the judge/mom duos a list of mandatory ingredients to feature in a Mother's Day dinner. Next, the chefs throw it back to their childhoods when Guy has them do all the shopping for their childhood favorite using kiddie carts. Mamma mia!
