Sprinkle some salt and ground black pepper on 350g of pork belly for seasoning. You can cut the pork belly in a honeycomb pattern to enhance the flavor.
Thinly slice 60g of green onions. The white part of the sliced green onions will be used to make green onion oil.
Cut 20g of ginger into thin slices, and cut 2 small onions into 5mm thick slices.
Prepare the soybean sauce by mixing 1 tbsp of soybean paste, 2 tbsp of soy sauce, 0.5 tbsp of sugar, 1 tbsp of red wine, 1 tbsp of honey, 1 tbsp of vinegar, 1 egg yolk, and 0.5ml of water.
Heat a pan with a little cooking oil and stir-fry the white part of the sliced green onions to make green onion oil. Remove the green onions after the oil is produced.
In the same pan, grill the seasoned pork belly until both sides become crispy. Maintain medium heat and slice the cooked pork belly into bite-sized pieces.
Once the pork belly releases its oil and becomes cooked, add the sliced ginger and stir-fry briefly.
Next, add the sliced onions and continue to stir-fry.
When the onions become semi-transparent, pour the prepared soybean sauce over the ingredients and simmer.
Turn off the heat when the sauce thickens slightly.
