Sprinkle both sides of fillets evenly with seasoning, pressing gently to adhere. Coat a large nonstick skillet with cooking spray; add oil, and place over medium-high heat until hot. Add fillets; cook 3 minutes on each side or until fish flakes easily when tested with a fork. Remove from skillet; set aside, and keep warm.
Add orange marmalade and remaining ingredients to skillet. Bring to a boil, and cook 1 minute. Pour sauce over fish, and serve immediately.
