Preheat oven to 500 degrees F.
Spray two pizza sheets generously with non-stick spray.
Divide dough into two. Hand stretch (or use a rolling pin if you prefer) the dough and place over top of the pizza pans. Stretch it and give the edges a bit more dough to get a thicker crust around the edge. Just use your fingers to push it and into to edges so it's about twice the height as it is in the middle.
Now spread the pizza sauce evenly over both pizzas.
Toss the mozzarella over top, you can use more or less depending on taste. We like ours pretty cheesy, but you can use less if you like prefer.
Place the pizzas in the oven, and cook for about 8 to 12 minutes, depending on how dark you like the bottom, and the brown you like the cheese. We put on on the bottom rack and one on the middle rack, then rotate them halfway through the cooking process.
Remove the pizzas from the oven.
Toss the arugula on top of the pizzas.
Spread the peaches evenly over the pizzas.
Then sprinkle the hazelnuts over top.
Use a pizza wheel to cut the pizzas while they're hot.
Serve with a big old peach pizza loving smile!
