Preheat oven to 400.
Roll out dough on floured surface. Transfer to prepared pizza pan or baking sheet. Brush on a little olive oil. Bake for about 10 minutes or until no longer wet looking. Remove from oven.
Top pizza crust with half the mozzarella cheese, shredded chicken, peach slices, gorgonzola cheese, and then finally the last of the mozzarella.
Bake for 10-12 minutes or until the crust looks a nice golden color.
Meanwhile, if you are using balsamic vinegar... heat the vinegar in a small saucepan and heat on medium high for about 5 minutes. The idea is to reduce the vinegar until its a thick glaze. You can also buy this in glaze form (like I have).
In a small bowl toss the arugula with very little olive oil and balsamic vinegar.
When the pizza has finished baking, drizzle with the balsamic glaze. Top with arugula. Enjoy!
