First I smash the noodles on the counter (while in the bag of course), then boil them with some water. I usually add the flavor packet thing about halfway through, along with some other spices and crap from the cupboard. I let it boil until there's just a little water left, and put it in the bowl. Crush up a handful of saltine crackers and I'm good to go!
Lately I've only been using half of the flavor packet because of the ridiculous sodium content (I know adding saltine crackers doesn't help, but hey).
