Preheat oven to 475 degrees. Roll out the pizza dough on a lightly floured surface or pizza peel (turning and flipping as you roll it out to prevent sticking).
Spread out the marinara over the dough leave about 1/2 inch around the edges. Top with mozzarella then peach slices and prosciutto (I like to tear the prosciutto and twist it slightly as I arrange it over the pizza). Sprinkle fresh basil over the pizza.
Bake at 475 for 12-14 minutes. Then turn on broiler and move the pizza to the top level and broil (to brown the cheese slightly) for 1 minute.
Remove from oven and top with fresh arugula. Drizzle with a thick balsamic and serve hot.
