Cook the rice with sufficient water and a soup cube. When it's done let it cool or keep it overnight in the refrigerator for best results. Heat a wok or a pan and add margarine. When it's hot add the vegetables and stir fry for a while. Then add the chopped garlic and ginger. Now make a well in the middle and drop the egg and scramble it well. Then add the chopped green onions and cooked rice and stir it until well mixed. Now add soy sauce and a little oyster sauce and stir well.
