Break up any large clumps in the cold rice, then place it in a large bowl.
Add the eggs, scallions, cheese, flour, soy sauce, and black pepper. Mix until the rice is evenly coated and the mixture holds together when pressed.
Heat half the oil in a large nonstick skillet over medium heat.
Spoon compact portions of the rice mixture into the skillet and gently flatten them into fritters.
Cook for 3 to 4 minutes per side until golden and crisp. Add the remaining oil as needed and repeat with the rest of the mixture.
Serve hot with yogurt sauce, salsa, or soy sauce.
