Korean Pork Bulgogi (cheater's version)

My son's favourite, he always ends up having two large plates of rice for this. I have to thank my Korean house painter for giving me such a good idea.  It is so simple, great for busy or lazy nights. Only 4 ingredients involved, yet is still a very tasty meal.


Ingredients
1 kg Pork neck
( thinly sliced, it would be the type that you use for Korean BBQ, I got it from local Korean grocery shop).
2  extra large onions (3 medium large), sliced thinly
1 big bunch of spring onions, cut them into about 3cm long.
1 bottle Pork Bulgogi marinade sauce (228ml), use it all. ( see picture below)

it is fairly cheap, cost me below A $3 actually

4 main ingredients

to marinade and rest in the fridge for a few hours

half way through, it will show up liquid all over the pan.
Don't worry, keep going, it will absorb back to the ingredients.

after 20 minutes, it is done,
very tasty meal

Method
In a large mixing bowl, mix in all prepared ingredients. Toss and mix well.
Wrap with cling wrap, keep in the fridge for a few hours.
Heat up oil on your nonstick pan, pour in everything. (use medium high heat all the way).
Set your timer to 20 minutes.
Stir and mix every now and then so that the meat get into the sauces.  Half way through, you see liquid appearing in the pan, don't do anything, just keep stirring and mixing...
When timer beeps, it is done.
