Cheap and Delish
Put a drop of oil into the frying pan or use a wok if u have one.
Throw the noodles in and add the (already cooked) chicken, and bean sprouts if needed.
Splash a generous amount of soy sauce in until the noodles and chicken are a mid brown colour.
Leave to cook for a couple mins, but keep stirrin them around. Taste to see if it needs any more soy sauce added.
Eat and enjoy when hot.
You could also replace the chicken with onions instead or just add onions to the dish.
