Combine cheese, mushrooms, parsley, salt and pepper. Place bread crumbs on a plate or a pie pan. Beat the egg and place in another shallow dish.
Make a slit in each pork chop about 3/4 the way through. Stuff with the cheese and musroom mixture. Dip and roll the chops in the egg then the bread crumbs. Use toothpicks to help keep them closed if you need to.
Place each pork chop in a greased baking dish, cover, and bake at 350 for 40 minutes.
