01 - Heat 1 tablespoon vegetable oil in a large wok or skillet over medium-high heat. Add diced chicken and cook for 4 to 5 minutes, stirring frequently until golden brown and cooked through. Transfer to a plate and set aside.
02 - In the same pan, add beaten eggs. Scramble gently until just set but still moist, then transfer to the plate with the chicken.
03 - Add remaining 1 tablespoon oil to the pan. Sauté minced garlic and ginger for 30 seconds until fragrant, being careful not to burn them.
04 - Add diced carrots to the pan and cook for 2 minutes. Stir in frozen peas and cook for another 1 to 2 minutes until vegetables are tender-crisp.
05 - Add chilled rice to the pan, breaking up any clumps with a spatula. Return cooked chicken and scrambled eggs to the pan. Toss everything together thoroughly.
06 - Drizzle soy sauce, oyster sauce if using, sesame oil, white pepper, and a pinch of salt over the rice mixture. Stir-fry for 2 to 3 minutes, ensuring everything is well combined and heated through.
07 - Stir in sliced green onions and adjust seasoning if needed. Serve immediately while hot.
