1. Preheat oven to 450°.
2. Combine marmalade, soy sauce, salt, black pepper, and garlic in a small bowl. Arrange salmon fillets, skin sides down, on a foil-lined baking sheet coated with cooking spray. Brush fish fillets evenly with half of marmalade mixture. Bake fish fillets at 450° for 4 minutes.
3. Heat broiler to high (do not remove fish from oven); broil fish 6 minutes. Spoon remaining marmalade mixture onto center of fillets. Broil fish an additional 3 minutes or until desired degree of doneness. Sprinkle fish evenly with green onions; serve with lemon wedges.
