Preheat the oven to 190°C/Fan 170°C/375°F. Brush 1/2 teaspoon butter over the bottom of a baking dish.
Spread apple slices in dish. In a small bowl, mix the flour, brown sugar and cinnamon and sprinkle over the apples. Sprinkle seasoned salt on both sides of the chops and place them over the apples.
In a medium saucepan, heat the apple juice and the butter to boiling over medium-high heat. Stir in the stuffing mix, diced apple and cranberries, if using. Cover and remove from the heat and let it stand for 5 minutes. Fluff the mixture with a fork, then scoop ¼ of the stuffing onto each chop.
Spray a sheet of foil with cooking spray and place sprayed side down over chops. Bake in the middle of the oven for 45 minutes. Remove the foil and bake for a further 10 minutes.
To serve, lift pork chops with stuffing to serving plates; serve apples on the side.
