1. Beat the eggs with the water in a bowl. Heat 1/2 teaspoon oil in a wok and add the egg mixture. Swirl it around to make an omelet. Transfer to a plate and allow to cool. When cool, cut into strips.
2. Heat the remaining oil, add the green onions and stir-fry for 2 minutes. Add the plain boiled rice and omelet strips.
3. Stir in the soy sauce, salt, and sugar and cook for 2-3 minutes. Serve in a large bowl.
