Accidentally, came across this recipe of Pailin's Kitchen on you tube where the chef has shared this easy and delicious stir fry chicken dish. This dish is cooked without adding any water.
According to the chef, the original recipe uses cooked boiled chicken which is chopped and fried with soy sauce. As I love ginger with chicken, this dish seems easy and simple to cook.  Easy and simple recipes without compromising the taste and flavour are always my favourite.I tried the recipe with slight modification to the method and no regrets, this is an awesome ginger flavoured chicken which is so much faster to cook compared to braising it.
If you are a ginger lover, I suggest to add more which I will do next time when I prepare this yummy dish again. As I do not have cilantro in hand, I have used spring onions.  I believe using cilantro will make the flavours more Thai......
