Rinse the rice under cold water, add to a pan, cover with 1 ¼ cups of cold salted water, and cook on a low heat until all the water has been absorbed.
Turn off the heat, cover the pan with a lid, and leave the rice to rest for 5 minutes.
Remove the lid, and use a fork to fluff the rice up. Set aside.
In a wok, heat up one tablespoon of vegetable oil, add the chicken and stir fry on a high heat for about 5 minutes until the chicken is golden brown and cooked through.
Add the chopped garlic, ginger, red chilli pepper, and broccoli broken into florets, and continue to stir for 3-4 minutes or until the broccoli has the desired texture, either a bit crunchy or soft.
To make the sauce, combine the chicken broth, oyster sauce, soy sauce and brown sugar, and pour it over the chicken and broccoli.
Mix the corflour with 3 tablespoons of cold water, and stir well, then add it to the pan, and mix everything together until the sauce thickens slightly.
Remove from the heat and serve with rice.
