Share the rocket between two serving plates and arrange the sliced mango on top. Remove the skin from the melon, cut the flesh into slices and arrange on the salads.
Tear or cut the mozzarella cheese into chunks or slices and share between the salads. Season with a little black pepper and arrange the slices of Parma ham on top. Drizzle with a little mango dressing and serve at once.
