Ohhh god, bad idea.
However my brother lived off it at one point and is still alive. Still eats it sometimes.
And remains as skinny as he ever was (Damn his stupid skinny-boy-genes!!!!!!)
I know someone who eats it ALLL the time and his skin is shit. (again, as a relatively skinny boy, puts on absolutely no weight from all the excessive calories, which I want to kill him for)
Whenever my boyfriend and I make it, I skip the sauce/seasoning and just add soy sauce to the noodles.. so it's not really mi goreng anymore. Minus a few calories, and doesn't make you feel sick after eating.
