Chicken rice need not be fattening if you're smart enough to not swallow the chicken skin.
Somehow, I think there are too many chicken rice stalls. But perhaps there are too many folks who eat chicken rice - and yet worry about its related health issues. How pitiful
If you worry too much about cholesterol, then eat mee siam without the hum! But if you're still worried, even after your hum-less mee siam, perhaps you should approach the chicken rice stall owner to share your concerns in a direct manner. That way, you will be able to benefit yourself and all those that eat chicken rice - and yet worry about it.
