Prepare the chicken: Cut the chicken breast into cubes. Heat oil in a pan, add the meat, season with salt and pepper, then cook for 6 to 8 minutes until cooked through. Pour the soy sauce over it and stir.
Cook the eggs: In another pan, crack the eggs into a little oil and make scrambled eggs. When done, set aside.
Fry the rice: In the same pan, heat a little oil, add the cooked rice, and fry for 3 to 4 minutes.
Combine: Add the eggs and chicken to the rice. Drizzle with soy sauce, stir together, and fry for another 2 to 3 minutes.
Serve: Sprinkle with finely chopped green onion and serve warm.
