Need help! Chinese chicken stalk

I knew the chef at my high school, he made a chinese chicken stalk everyday for lunch, you got the noodles then poured in the doup, anyway he told me he used boxed or store bought chicken stalk.
The ingrediants are:
Chicken stalk
Powdered Ginger
Rice wine vinegar
Green onions at the end.
If any of you have worked with anything like this it would be so helpful, he doesnt know the portions because he uses such large quantities. Thanks
