Start by cooking the long-grain rice according to the package instructions.
Heat oil in a large skillet or wok over medium-high heat.
Toss in the diced chicken and cook until lightly browned and thoroughly cooked.
Add minced garlic and finely chopped chillies, sautéing for a minute until fragrant.
Incorporate the red bell pepper and green peas, cooking for another 3-4 minutes.
Push the chicken and vegetables to one side of the skillet, and on the other side, add in the cooked rice.
Drizzle the soy sauce and oyster sauce over the rice.
Mix everything together, ensuring the rice is well coated with the sauces.
Season with salt and ground black pepper.
Finish by tossing in sliced green onions.
