Lightly toast the pine nuts in a dry skillet/frying pan or on a baking sheet under the broiler//grill, keeping a close eye as they can quickly burn. Set aside to cool.
Slice the mozzarella into bite sized pieces and cut the peach into slices.
Put the arugula in the bottom of a serving bowl or divide between two individual bowls. Arrange the mozzarella and peach slices over the top.
Take slices of the Prosciutto de Parma and separate into 2-4 pieces so that you can roll the pieces into a little rose shape. Place the ham roses in the salad.
Drizzle over the toasted pine nuts, roughly shred the mint leaves and scatter over the top then drizzle on the vinegar and olive oil. Add a little salt and pepper, to taste, then serve.
