Prepare 2 sets of ingredients:
To cook: Fry some sliced garlic in a little oil for a minute or two, then pour in the marinated chicken and stir-fry. Add some water or in my case, I used some of the herbal soup I was boiling instead so that the gravy will be more tasty. Add oyster sauce, dark sauce and a little sugar if you like. The thicken the sauce put in a few teaspoons (about 3) of cornstarch. Continue to stir.
Lastly, put in the yee-foo noodles and let it soften in the gravy. Use a pair of chopsticks or fork to mix the noodles well.
