What to do with left-over balsamic barbecue sauce? I know... make a barbecue chicken pizza! Seriously this might be the best pizza ever. It comes really close to The Works pizza at Mellow Mushroom. A little mozzarella, spinach, red onion, bacon, and chicken was the perfect combination to go with the left-over sauce. I'm not trying to brag but it was really delicious. If you like pizza you gotta make this one!
