For each serving: Heat oil in large skillet over medium heat and sauté onion 1 minute. Stir in remaining ingredients except salmon. Set aside. Heat oil in another large skillet over high heat. Add 1 or 2 salmon fillets. Cover; reduce heat to medium-high. Cook 6 minutes, turning over halfway through. Add to pan approximately 1 1/2 ounces soy sauce mixture per fillet. Cook 1 minute to thicken glaze slightly. Turn salmon to coat; plate with sauce.
