I don't eat pork (doesn't agree with me) but I would imagine you could make some lattice work on the bottom with some whole carrots, celery stalks, and onions, pour some chicken or beef broth over that to keep the meat moist while it cooks, then throw the pork loin on that. Suppose you could dribble some broth onto the top of the roast or not. Roast that and you'd get something more edible. Save the apples and just bake them separately in the oven with a little bit of brown sugar or honey if you want something sweet as a side.
