Clean and wash the rocket. Remove seeds from the papaya. Peel the flesh and cut into 4 slices. Peel the pineapple slices, cut out the inner firm stalk. Cut the slices into thirds.
Cut the ham slices in half lengthwise. Wrap 1/2 slices of ham around each piece of fruit. Heat oil in a coated pan. Fry the fruit pieces for about 3 minutes at medium heat, turning them over.
Remove, pour vinegar and 2 tablespoons of water into the pan, season with sugar and pepper. Arrange pineapple and papaya pieces with the rocket on a plate. Drizzle marinade over them. Sprinkle parmesan slices over it.
