WASHINGTON (AP) — An Air Force chef and a Marine Corps chef, both crowned “Chopped†champions during Jill Biden 's appearance on a military-themed episode of the Food Network show, spent Friday whipping up lemon-herb scallops and osso buco in the White House Navy Mess.

Air Force chef Opal Poullard, 37, and Marine Corps chef Dustin Lewis, 34, accepted the mission from the first lady, who made a surprise appearance in a May episode of “Chopped,†as part of her White House initiative to support active-duty and retired service members, their families and caregivers.
