Omar Epps -- Lunch Is On Me! -- Drops $1500 For Grub Truck

None of Omar Epps' co-stars on the TV show "Resurrection" were complaining about the food on the set today ... that's because Omar dug deep into his pockets to pay for lunch ... for everybody!

The show is shooting in Atlanta ... Omar dropped $1,500 to rent the Sweet Auburn BBQ food truck ... which dished up grub to about 90 cast members, crew and extras.

Our BBQ sources tell us the Dirty South package-- brisket, pork, and chicken -- is to die for.

Fun Fact: "Resurrection" is a show about people who die ... and return from the dead.
