This was an excellent way to eat Thanksgiving turkey leftovers when you are getting a little tired of eating turkey. I caramelized the onions by sauteing first and finishing with balsamic vinegar. I made the pizza on a thin crust Boboli, which I normally don't like, but it worked very well for this pizza. It reminded me of a barbecued chicken pizza, only not as sweet. I used more balsamic than the recipe calls for when marinating the shredded turkey. I was out of arugula, so I put sliced basil on top.
