Prepare the pizza crust according to the instructions.
When the crust is done baking, remove it from the oven and top it with the sauce. Layer on the cheese. Tear the prosciutto into smaller pieces and arrange on top of the cheese. Bake for 12-15 minutes until the cheese has melted and is starting to brown, and the edges of the prosciutto are crispy. Let cool for 5 minutes before slicing. Garnish with arugula and drizzle with olive oil before serving if desired.
