Crumble the rice with your fingers to break it up. Set aside.
Beat the eggs well with 1 tablespoon water in a small bowl.
Heat 1 tablespoon of the oil in a wok or large skillet over high heat. Once hot, add the garlic and fry for 30 seconds. Add the eggs and stir quickly until just set, breaking them up into pieces. Remove from the wok and set aside.
Add remaining oil and heat. Add onion and saute 60 seconds. (If using raw meat, add with onion and stir fry until cooked.)
Add rice, salt and peas and carrots (if using cooked meat, add now). Stir constantly until the ingredients are mixed up and heated through, about 8 minutes.
