Take one slice of pork and top it first with one piece of parma ham or bacon and then top the ham (bacon) with one sage leaf.
Secure the ham (bacon) and the sage leaf with one tooth pic, making sure the meat stays flat. Continue with the remaining ingredients.
Heat some olive oil in a non-stick pan.
Put some of the pork pieces , sage side down into the pan and fry them for 2 to 3 minutes.
Season them with a little bit of salt and some freshly ground black pepper, while they frying sage side down.
When the sides of pork meat change colour you can turn the pieces around and fry the other side for 1 to 2 minutes. The pork must be done.
You want some caramelization on the meat, so the temperature should be medium to high.
When you are finished with all the meat and it is resting on a plate, turn the heat on high and deglace the pan with the sherry. Cook the liquid for 2 to 4 minutes.
Make sure that you catch all the little bits and pieces from frying the meat.
Pour the pan juices over the pork and serve.
You can serve the saltimbocca-style pork warm or at room temperature.
