MasterChef USA

Former "Masterchef" contestants return; chefs compete in head-to-head audition battles.

With only six aprons left, the judges give a lucky few chefs a chance to return to the kitchen.

All 20 chefs must cook something inspired by the dish that originally sent them home.

Cocktail connoisseur Shaun O'Neale gives the chefs their first mystery box challenge.

The top 18 travel to the U.S. Coast Guard base in Los Angeles for the first team challenge; the chefs work together to create a lunch for more than 100 men and women; one contestant will be eliminated.
