I barbeque a mock gyro - combining a 5 pound butterflied leg of lamb with a 2 pound tenderized beef round steak - both seasoned with a combination of thyme, salt, pepper, coriander and placed in a marinade (oil, lemon juice, garlic, onion) overnight . Place the beef on top of the flesh side of the lamb - roll it up - tie - place on a rotisserie - roast for 21/2 hours or so. Serve in pita bread. top with tomatoes, parsley, yogurt etc.
