What ever you would normally eat with the rice is where the money shot usually is. This is easily tested with most high carb foods, by looking at if you would eat that food by itself. E.g. curry and rice, fish and chips a traditional roast with potatoes. I would say if you remove the carby elements the rest of the meal can stand by itself or you can replace the higher carby element with a non starchy choice.
Obviously chips are the exception to the rule.
