Choose your noodles. A lot of the Asian noodles I have purchased are already bundled in one or two person servings.
Bring an appropriate pot of water to boil, then add noodles and cook according to package.
In a bowl (I mix and serve in the same one), mix together whichever of the above ingredients you prefer. You can go salty, spicy, sweet, creamy. I personally would not mix the mustard and PB together, but hey.
Add the noodles (I scoop from the pot for some added liquid), stir and eat! Yummy!
Great hot or cold. Also yummy with some egg or sliced up leftover meat!
