Pop star and trained chef Kelis judges a meaty quickfire challenge, and actor Christina Hendricks oversees a 60s themed elimination challenge.

The masters trade their chef hats for hairnets as they take over a fast food drive-thru, needing to serve their meals in two minutes.

The chefs split into pairs and each one chooses a box containing a secret ingredient. Each chef must make a dish with both of the secret ingredients.

Crickets, nightcrawlers, and beetles are on the menu for the quickfire, while the elimination challenge has the chefs selling their dishes for $100 a plate to earn money for a charity fundraiser.

The chefs prove nutritious food can still taste great as they team up to provide breakfast, lunch, and dinner for the cast of The Biggest Loser.
