Preheat oven to 400°.
Combine first 9 ingredients in a bowl; brush both sides of fish with the orange mixture. Reserve remaining orange mixture. Place fish on a broiler pan coated with cooking spray. Bake at 400° for 15 minutes or until fish flakes easily when tested with a fork.
Place remaining orange mixture in a small saucepan; bring to a boil, and cook until reduced to 1/2 cup (about 2 minutes). Serve with fish, and garnish with orange wedges and parsley, if desired.
