Preheat oven to 425°.
Combine first 4 ingredients in a large baking dish. Add pork, turning to coat. Marinate in refrigerator 30 minutes, turning pork occasionally.
Place stuffing mix in a food processor, and process until finely crushed. Pour stuffing mix into a shallow dish or pie plate. Remove pork from baking dish, and discard marinade. Dredge both sides of pork cutlets in stuffing mix, pressing to coat thoroughly. Place pork cutlets on a baking sheet coated with cooking spray, and bake at 425° for 12 minutes or until done. Garnish with thyme sprigs, if desired.
