Put salmon and 1/3 c teriyaki marinade in a large ziplock bag and marinate for 20 minutes. Discard marinade and grill salmon until cooked through and flaky or heat a non-stick skillet or grill pan and cook on the stove top over medium heat until cooked through - about 5 minutes/side. In a skillet, saute the zucchini for 3-4 minutes. Add 2-3 T of the teriyaki sauce and cook until the zucchini is done. Serve the zucchini over or next to the salmon and sprinkle with sesame seeds and additional teriyaki sauce. Combine all ingredients and stir until sugar is dissolved.
