Creating Teriyaki Salmon with Steamed Vegetables can be straightforward if you follow these simple steps:

1. Prepare the Marinade: In a small saucepan, combine soy sauce, brown sugar, rice vinegar, garlic, and ginger. Heat over medium heat until the sugar dissolves.

2. Thicken the Sauce: In a separate bowl, mix cornstarch and water. Add this mixture to the saucepan, stirring continuously until the sauce thickens. Remove from heat and set aside.

3. Marinate the Salmon: Place the salmon fillets in a shallow dish and pour half of the teriyaki sauce over them. Allow them to marinate for 10-15 minutes to absorb the flavors.

4. Prepare the Steamed Vegetables: While the salmon is marinating, prepare your vegetables. Wash and chop the broccoli, carrots, and snap peas.

5. Steam the Vegetables: In a steamer basket over boiling water, add the vegetables. Cover and steam for about 5-7 minutes or until they are tender-crisp.

6. Cook the Salmon: In a non-stick skillet, heat sesame oil over medium heat. Remove the salmon from the marinade and place it in the skillet. Cook for about 4-5 minutes on each side, basting with the remaining teriyaki sauce.

7. Serve the Dish: Once the salmon is cooked through and has a nice glaze, remove it from the heat. Arrange the steamed vegetables on plates and top with the teriyaki salmon.

8. Garnish: Sprinkle sesame seeds and sliced green onions over the salmon and vegetables for an added touch of flavor and presentation.
