All-Star chefs Ron Ben-Israel, Penny Davidi, Pat Neely and Justin Warner compete to win up to $20,000 for charity. First up, chefs must make their favorite lunch using a ridiculous Red Light Special. Next, chefs must rummage through the Clearance Carts to make their best noodle dish. Finally, who will reign supreme making their showstopping dinner using the four uncanny ingredients from the Fieri Food Pyramid?

It's a star-studded event as Food Network Stars Eddie Jackson, Aaron McCargo Jr., Damaris Phillips and Justin Warner descend on Flavortown Market. First, the stars must create a delicious family dinner using only ingredients that fit into a purse-size shopping bag. Next, the stars use refrigerator magnets to come up with the round's dish: spicy pork seafood casserole. Finally, a game of Grocery Golf determines the ingredients in their best lamb dish, with the victor winning up to $20,000 for charity!

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!
