A sweet, tangy and salty mixture of soy sauce, rice vinegar and honey does double-duty as marinade and sauce. Toasted sesame seeds provide a nutty and attractive accent. Make it a meal: Serve with brown rice and sautéed red peppers and zucchini slices.

1 scallion, minced
2 tablespoons reduced-sodium soy sauce
1 tablespoon rice vinegar
1 tablespoon honey
1 teaspoon minced fresh ginger
1 pound center-cut salmon fillet, skinned (see Tip) and cut into 4 portions
1 teaspoon toasted sesame seeds (see Tip)

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, 6 to 10 minutes. Drizzle with the reserved sauce and garnish with sesame seeds.

How to skin a salmon fillet: Place skin-side down. Starting at the tail end, slip a long knife between the fish flesh and the skin, holding down firmly with your other hand. Gently push the blade along at a 30° angle, separating the fillet from the skin without cutting through either.

To toast sesame seeds, heat a small dry skillet over low heat. Add seeds and stir constantly, until golden and fragrant, about 2 minutes. Transfer to a small bowl and let cool.
