Easy recipe: Zha jiang mian or fried noodles sauce

So I actually got this recipe from my mother and it's not inspired by any recipes on the internet but if you want an equivalent that seems to be a good match or better measured, this one here should work:

Ingredients:
1 TBSP oil or sesame oil
1 onion chopped - I actually use ginger instead sometimes like photoed here
1/4 cups of soybean sauce
1 TBSP corn starch - we use tapioca starch here in Taiwan to be mixed with 1 cups of water
1 lb of ground pork (or beef, or turkey or whatever you have, this is very flexible)

Optional:
If you have leftover vegetables like I did with mushroom you could put them in also. This is a very forgiving and flexible recipe.

Steps:
Stir-fry onions until soft. Then pour in the meat until browned. Mix the cornstarch with water and the soybean sauce and pour into the pot. Mix for 3-5 minutes on medium heat.

Cook whatever noodles you have on hand and mix it in.

You can put in whatever vegetables you have for garnish also.

Here's the end result.

You can use whatever sauce you have on hand:
