Place the broccoli in a steamer basket; place in a saucepan over about 1 inch of water. Bring to a boil; cover and steam for 5-7 minutes. Broccoli should be crisp tender.

While broccoli is cooking, combine sugar, oil, soy sauce and vinegar in a small saucepan over medium heat. Cook, stirring continuously until sugar is dissolved.

Place broccoli to a serving bowl. Drizzle the sauce over the broccoli and then sprinkle with the toasted sesame seeds.
