In a small mixing bowl, combine the low-sodium soy sauce, honey, rice vinegar, sesame oil, grated ginger, and minced garlic. Whisk these ingredients together until they are well blended; this mixture will serve as your flavorful teriyaki marinade.
Take the salmon fillets and place them in a shallow dish. Pour the marinade over the fillets, ensuring they are well coated. Allow the salmon to marinate for approximately 10 minutes.
While the salmon is marinating, preheat a large non-stick skillet or a cast-iron skillet over medium-high heat.
After 10 minutes, carefully remove the salmon fillets from the marinade, reserving the marinade for later use. Gently place the fillets skin-side down into the hot skillet. Cook undisturbed for about 4 minutes to allow the skin to become crispy.
Once the skin is crispy, carefully flip the salmon fillets over to the flesh side. Lower the heat to medium, and pour the reserved marinade over the fillets. Continue cooking for another 3-4 minutes, basting the salmon with the sauce as it cooks.
If you prefer a thicker sauce, stir in the cornstarch mixture at this stage and allow it to simmer for an additional minute, or until the sauce has thickened to your liking.
Check the salmon for doneness; it should easily flake with a fork. When cooked to your preference, remove the skillet from heat.
Before serving, garnish the salmon with a sprinkle of sesame seeds and a scattering of chopped green onions for a pop of color and flavor.
Notes
Serve the salmon on a bed of steamed rice or alongside sautéed vegetables for a well-rounded meal.
