"My dad, who loves onions, invented this tasty side dish," says Marcia Preston of Clear Lake, Iowa. "The tender seasoned onions go well with all types of grilled meat, so we enjoy them frequently. Cleanup is a breeze, too."
Divide onions between two pieces of double-layered heavy-duty foil (about 22 in. x 18 in.) coated with cooking spray. Top each with butter, oregano and pepper. Fold foil around the mixture and seal tightly. Grill, covered, over indirect heat for 30-40 minutes or until onions are tender.
