Steam broccoli for 5 to 8 minutes or until it is as tender as you like it.
Combine the orange juice, honey and ginger in a small saucepan. Bring it to a boil. Mix the cornstarch with water and stir until it is smooth. Add the cornstarch slurry mixture to the sauce pan and return the mixture to a boil, stirring constantly. Cook the sauce for 1 minute or until it is thickened. Remove the pan from the heat. Stir in the lemon juice and sesame oil.
Place the steamed broccoli into a serving bowl. Top it with the sauce and sprinkle it with the sesame seeds.
