After prep of veggies, cutting & slicing....

boil chicken in water, put enough water to cover the chicken in sauce pan. Add bay leaves, 1/2 or 1 onion, 3 crushed garlic cloves, sliced ginger, salt & pepper (to taste) and 1/4 chicken broth cube.

Boil 15-20 minutes, depending on size / quantity of your chicken.
For me, I prefer with bones and skin, as it is just tastier. :)

Tip:. Since you are boiling the chicken, why not create a chicken broth soup with vegetables as well. Just get some leafy green veggies in your fridge. I added some sliced Taiwan pechay or bok choy, leek leaves + ends, Chinese cabbage or cabbage is good too, chicken skin from breasts (if any), a few pcs wansoy or coriander leaves (add at the end). And voila, now you have a delicious veggie broth as well!

Season with salt and pepper, to taste, sprinkle remaining chicken bullion broth cube, to desired taste. If it's too dry, add a spoon of the broth.

Add heat or spicy taste with diced bell pepper or chili, if desired.

Mix well. Transfer to a serving plate.
Top with diced celery stalk.
Set aside and prepare the sauce.

SAUCE RECIPE-

in same wok, add 1/2 c water, drop in half of the remaining minced garlic. Simmer a few minutes.

Add the 3 regular spoonful of soy sauce. Use whatever you have, you can always adjust with water or sugar if it's too salty.

Add the sugar. Mix well.
Taste and add the rest of the garlic if it is lacking in garlic flavour.

There should be a balance of salty, sweet and garlicky flavour. Add a little more sugar if you prefer more sweeter than salty.

When you get the taste you like-

In 1/4 c remaining water, mix in 2 regular teaspoons (not heaping) of cornstarch. Dissolve well.

Add to wok. Stir well.
Let it simmer until it becomes syrupy.

Sauce is ready when it is like syrup.

I used brown sugar so my sauce appears darker. My soy sauce was also dark.

If you use white sugar and lighter color soy sauce, it will appear like caramel in color. This is okay too. What matters is the taste. :)

Serve sauce on the side-
to be spooned over the veggie-chicken mix.
Some people like a little sauce, as for me, I like a lot :)
