1. Combine first 6 ingredients in a zip-top plastic bag. Add tenderloin; seal bag, and marinate in refrigerator at least 2 hours.
2. Preheat oven to 450°.
3. Remove tenderloin from bag, reserving marinade. Place tenderloin on a broiler pan coated with cooking spray. Bake at 450° for 25 to 30 minutes or until a thermometer registers 155° (slightly pink). Cover with foil, and let stand 10 minutes.
4. While pork stands, place reserved marinade in a small saucepan. Bring to a boil over medium heat. Cook 2 minutes, stirring constantly. Stir in green onions. Slice pork, and serve with sauce.
