Place slice of bread in a food processor, and pulse 10 times or until coarse crumbs measure 1/4 cup. Combine the breadcrumbs, 1/4 cup chopped parsley, cheese, and 2 teaspoons thyme in a shallow dish. Sprinkle pork with salt and pepper. Combine Dijon mustard, fennel seeds, and garlic in a small bowl. Rub pork with mustard mixture, and dredge in breadcrumb mixture.
