1 scallion, minced
2 tablespoons reduced-sodium soy sauce
1 tablespoon rice vinegar
1 1/2 tablespoon honey
1 teaspoon minced fresh ginger
1 pound center-cut salmon fillet, skinned and cut into 4 portions
1 teaspoon toasted sesame seeds
Whisk scallion, soy sauce, vinegar, honey and ginger in a medium bowl until the honey is dissolved. Place salmon in a sealable plastic bag, add 3 tablespoons of the sauce and refrigerate; let marinate for 15 minutes.
Reserve the remaining sauce.>
Preheat broiler. Line a small baking pan with foil and coat with cooking spray.
Transfer the salmon to the pan, skinned-side down. (Discard the marinade.) Broil the salmon 4 to 6 inches from the heat source until cooked through, 7 to 10 minutes. Drizzle with the reserved sauce and garnish with sesame seeds.
