Take pizza dough of of the fridge before hand so it can reach room temperature.
Preheat the oven to 450 degrees. Coat a baking sheet or pizza pan with a thin layer of olive oil or a dusting of cornmeal. On a clean working surface dusted with flour, gently stretch the pizza dough to fit your pan, roughly a 12" circle or 10" x 6" rectangle will do. Gently place dough in the pan, prick all over with a fork and lightly brush with olive oil. Place in the oven and bake until it begins to turn golden, about 10 minutes. Remove from oven, layer on the prosciutto, peach slices and dollops of ricotta. Place back in the oven and bake for another 5 minutes, until prosciutto crisps. Remove from oven, top with arugula and torn basil leaves. Drizzle with olive oil and balsamic vinegar and finish with a sprinkle of flaky salt and freshly ground pepper.
