Add the oil to your wok or pan and set the heat to medium high.
Add the chicken and spread it out so it forms one layer.
After a minute or two, add the garlic and ginger.
Once fragrant, after about another minute, add the broccoli as well.
Give the sauce a quick stir to dissolve the corn starch that started separating, then pour it into the work or pan.
Stir until the sauce thickens, for about another minute.
Transfer to plates or bowls and immediately serve with rice.
