Prepare the Marinade: In a bowl, whisk together the honey, soy sauce, Dijon mustard, olive oil, minced garlic, and grated ginger until well combined.
Marinate the Salmon: Place the salmon fillets in a shallow dish or a resealable plastic bag. Pour the marinade over the salmon, ensuring each fillet is well-coated. Marinate for at least 30 minutes, or up to 2 hours in the refrigerator for deeper flavor.
Preheat the Oven: Preheat your oven to 400°F (200°C).
Bake the Salmon: Remove the salmon from the marinade and place it skin-side down on a lined baking sheet. Reserve the marinade for basting. Bake the salmon in the preheated oven for about 12-15 minutes, or until the salmon flakes easily with a fork. During the last 5 minutes, brush the salmon with the reserved marinade for a glaze.
Serve: Once cooked, remove the salmon from the oven, and let it rest for a couple of minutes. Season with salt and pepper to taste.
Garnish and Present: Garnish with sliced green onions and sprinkle sesame seeds on top if desired. Serve with your choice of sides like steamed vegetables or rice.
