Combine pine nuts, 1/2 teaspoon salt, and 1/4 teaspoon white pepper. Sprinkle 1 tablespoon nut mixture over each fillet. Coat with cooking spray.
Heat olive oil in a large heavy skillet coated with cooking spray over medium-high heat. Place half of fillets, nut side down, in skillet. Cook 3 minutes or until nuts are lightly browned. Remove from skillet.
Place salmon, nut side up, in a 15- x 10-inch jellyroll pan coated with cooking spray. Repeat with remaining fillets. Sprinkle fillets with remaining 1/4 teaspoon salt and 1/4 teaspoon white pepper. Bake at 400° for 11 minutes or until fish flakes with a fork.
