Food dreams are often symbolic so it's really hard to pin down a good interpretation.
Since rice is a central part of this meal, it could signify abundance or some association with a more global idea you have.
Chinese food is also associated both with "going out" and with "taking in" so you might consider which of these were in the dream. Another consideration is the Eastern analysis which tends to direct the attention to a decific in the diet.
Or like so many other dreams, maybe you are just hungry and like Chinese food!
