Mash the potato with a fork, then add the ham, egg yolks, parsley, milk and mustard. Mix until well combined. In a separate bowl, whisk the egg whites until light and fluffy. Fold the egg whites into the potato mixture and spoon it into the potato shells. Top with the cheese and bake for 6-8 minutes until golden, then serve.
