In a saucepan, bring the broccoli to a boil (in a marginal amount of water). Reduce the heat, cover and cook for another five to eight minutes.
Meanwhile, in another pot, combine the cornstarch, bouillon granules and sugar. Add the water, orange juice and peel, and stir until the mixture is blended. Then bring to a boil, and stir for two minutes until it thickens.
Finally drain the broccoli, place it in a serving bowl, and drizzle the sauce over top. Garnish with orange slices before serving."
