You want to time it so that your pork and your noodles are ready to go at the same time. The pork takes about 10 minutes to cook. My noodles took 5. So I started the pork, then about halfway through, put my noodles on to boil. It's better if the pork has to wait, than the noodles, because the pork really can't be too crispy, but the noodles will get gluggy, so work it out, based on your noodles' cooking instructions.
