Make the Teriyaki Sauce: In a small bowl, whisk together the soy sauce, honey, sesame oil, rice vinegar, ginger, and garlic until well combined.
Marinate the Salmon: Place the salmon fillets in a shallow dish and pour half of the teriyaki sauce over them, letting them marinate for at least 15 minutes.
Cook the Grains: While the salmon is marinating, cook the quinoa or brown rice according to package instructions. Fluff it with a fork once done.
Prepare the Vegetables: Steam the broccoli florets and sliced carrots in a pot for 5-7 minutes until tender but still vibrant in color.
Cook the Salmon: Heat a non-stick skillet over medium heat. Place the marinated salmon fillets skin-side down and cook for 4-5 minutes per side, brushing with remaining teriyaki sauce until cooked through and flaky.
Assemble the Bowls: In a bowl, layer the quinoa or rice at the bottom, followed by steamed vegetables and a salmon fillet on top.
Garnish: Add sliced avocado, chopped green onions, and sprinkle with sesame seeds for added flavor and crunch.
Serve: Drizzle any leftover teriyaki sauce over the assembled bowls for extra flavor.
