Heat the remaining tablespoon of oil in the pan over a high heat. Add the onion and pepper, then season with salt and pepper. Fry for 2 minutes, then add the garlic and ginger, if using, and fry for a further minute.
Reduce the heat to medium, add the cooked rice, spring onions, peas, if using, scrambled egg and soy sauce. Toss together and cook for 3–5 minutes, or until heated through.
