Bring two quarts of water to a boil in a small pot and add 1 teaspoon of salt. Gently place the pork belly into the water and lower the heat to a slow boil (just above a simmer). Cook the pork uncovered for about 45 minutes or until fork tender. Remove the pork to a plate. (Set aside the pork stock you have now created and use it for a ramen or noodle soup or cooking stock later!)
While the pork is cooking, chop the cilantro and scallion and set them aside separately. Finely mince the garlic cloves or use a garlic press and set that aside. Chop your peanuts and set them aside as well.
Break up the dried chilis and toast them in a pan with 1 tablespoon of oil for a couple minutes. Put the oil and chili into a small bowl. Next, add the chili oil, peanut butter, spicy bean paste, soy sauce, and half of the minced garlic. Mix well. These are the basic ingredients and you can adjust amounts according to your preference when you make it. There are really no rules here! I sometimes add some of the pork broth which thins out the sauce and adds even more flavor. Set the sauce aside.
Now you are set to slice the pork. The best way to do it is to slice the pork while it is still warm and make your slices as thin as possible. We were in a hurry, so the slices in the picture a bit too thick. Then you can arrange the slices on a plate like I did, or you can toss the pork in the sauce. Taste for salt and adjust seasoning.
Then sprinkled the scallion, cilantro, and crushed peanuts over the dish and pile the remaining minced garlic on top. Serve!
