Preheat oven to gas 4, 180ºC, fan 160ºC. Place an empty baking tray in oven to heat through.
Place the pork steaks on a board, and with a sharp knife carefully make a slit horizontally into the non-fat edge of the pork. Continue until you have created a shallow pocket to stuff.
Take a slice of cheese and two sage leaves and push into the pocket. Season and wrap each steak in a slice of ham or bacon.
Heat oil in a frying pan and seal steaks on both sides. Place on the hot tray (that has been preheated in the oven) and cook for about 15-20 minutes until browned and cooked through.
Serve with seasonal green salad, crushed new potatoes and mixed olives.
