Line a baking sheet with aluminum foil and place a wire rack over top. Spray the rack with nonstick spray.
In a small bowl combine olive oil, sesame oil, rice vinegar, brown sugar, soy sauce, and ginger. Whisk well. Transfer 1 tablespoon of the liquid to a small jar (for the glaze) and set aside. To the remaining liquid, add garlic and whisk again. Pour liquid in a dish or plastic bag. Add salmon, making sure it is covered in marinade, and refrigerate for 30 minutes.
Meanwhile, to make the glaze, add honey to the 1 tablespoon of reserved marinade. Shake or whisk well to evenly combine.
Preheat the broiler in your oven.
Place salmon directly on the prepared wire rack. Sprinkle with a little bit of salt and pepper. Place the baking sheet directly under the broiler. Cook for 10-12 minutes (depending on the salmon’s thickness) until opaque and easily flakable with a fork. In the last minute of cooking, sprinkle the surface of the salmon with sesame seeds. (The seeds will toast under the broiler.)
Remove salmon and drizzle with the glaze and the green onions. Serve immediately.
