Place the chicken between 2 sheets of plastic wrap and flatten with a rolling pin. Sprinkle the chicken with the parmesan and wrap with prosciutto. Heat the oil in a large non-stick frying pan over high heat. Cook the chicken for 3–4 minutes each side or until cooked through. Place the tomato and basil in a bowl, drizzle with extra oil and vinegar and toss to combine. Serve with chicken sprinkled with extra parmesan. Serves 4.
