In a small bowl, combine the cheese, bacon, parsley, and 1/8 teaspoon black pepper.
Lay the chop flat on cutting board, and with a sharp knife held parallel to the board, cut a pocket into the pork, going all the way to the bone, but leaving the sides intact. Stuff cheese mixture into pocket, and close with a wooden toothpick. Brush meat with oil, and season with salt and more black pepper.
Lightly oil the grill grate. Grill over medium heat for 5 to 8 minutes on each side, or until pork is done. Careful not to overcook!
