In a mixing bowl, whisk together the soy sauce, olive oil, honey, minced garlic, grated ginger, sesame oil, and black pepper until well combined.
Place the salmon fillets in a baking dish or a resealable plastic bag. Pour the marinade over the salmon, ensuring that each fillet is coated evenly. If using a bag, seal it and gently massage the marinade into the salmon.
Marinate the salmon in the refrigerator for at least 15 minutes, or up to 2 hours for deeper flavor.
Preheat your grill or oven to 400°F (200°C).
Remove the salmon from the marinade, allowing any excess to drip off. Discard the used marinade.
Place the salmon on the grill or in a baking dish (if using the oven). Grill for about 5-6 minutes per side, or bake for approximately 10 minutes, until the salmon is cooked through and flakes easily with a fork.
Serve the salmon with fresh lemon or lime wedges for an extra burst of flavor.
