Prepare the ingredients. Cold leftover rice works best. Break up any clumps of rice with your hands, beat the eggs, and finely chop the scallion.
Heat the oil. Heat the peanut oil in a wok or on a griddle over high heat.
Stir-fry the rice. Add the rice and stir-fry rapidly until the rice is heated through.
Cook the eggs. Make a well in the center of the rice and pour in the beaten eggs. Scramble the eggs in the well until cooked through, then stir-fry them into the rice until evenly combined.
Add the seasonings. Add the pepper and scallions and stir-fry for about 30 seconds.
Finish. Add the salt or soy sauce and stir-fry for just a few seconds. Remove from the heat and serve immediately.
