PHILADELPHIA–Celebrity chef Robert Irvine helped kick off a $700,000 WaWa fundraising campaign for the USO and make a few tons of hoagies in the process.

For every Hero Hoagie sold through July 4, Wawa will donate $1 to the USO.

“The USO is a fantastic, amazing organization that deserves all of our support,” said Irvine, who spent his morning building and delivering thousands of his signature hoagies to active duty military, veterans and first responders in the Philadelphia area.
