Slice the pork into about a 1/4-inch thick, and 1-inch wide.
Place the wok over high heat.
Once the wok is hot enough, add the pork belly slices and spread them evenly on the wok.
Cook for about 20 minutes --- mix often.
Adjust the heat to medium-high once the pork belly slices are almost cooked.
Add the minced garlic.
Cook for about a minute or until the garlic becomes fragrant.
Add the salt, pepper, and chili.
Cook for about 2 minutes --- keep mixing the entire time.
Turn the heat off.
Use a spider strainer to scoop the pork and transfer them into plates.
Garnish your salt and pepper belly slices with chopped spring onions (and more sea salt, if desired) and serve.
