When I worked as restaurant supervisor at the Holiday Inn Sacramento Northeast years ago, this was a favorite among many guests....and one of mine, too!The combination of the balsamic vinegar and mozzarella cheese adds a delightful taste to this vegetarian dish. Even meat-lovers will flip for this meatless burger. Guaranteed to satisfy your next BBQ crowd!
