Food Network stars Eddie Jackson, Aaron McCargo Jr., Damaris Phillips and Justin Warner descend on Flavortown Market; in the first challenge the stars must create a family dinner using only ingredients that fit into a purse-sized shopping bag.

The second round begins for the eight competing chefs, and the judging gets tougher.

Flavortown judges face off in three one-on-one battles.

Alton Brown enlists past 'Food Network Star' season winners Damaris Phillips and Justin Warner to give Mr. Flay the runaround in his own kitchen. The tables turn and the stakes heighten.

Guy Fieri challenges his talented chef friends to take a burger beyond the basic patty and bun. Antonia Lofaso combines sirloin, brisket and braised oxtail while Aaron May makes a crunchy, tortilla-wrapped green chile burger.
