Likewise (although my single portion is for two people).
Proper fried rice has to be pre-cooked and cooled - otherwise the starches are not cooked properly and don't fry will (turn into a glutinous mass).
Makes it easy to use up left-overs generally and is a good 'just-in-from-work-and-tired' meal.
(Something like cut up baccon/sausages/chicken/cold roast pork, stir fry till cooked with random assortment of sauces/spices/veggies, microwave pre-cooked egg-fried rice and serve with generous glass of something alcoholic)
