Cut the pork belly into small cubes, keeping the skin intact.
Season the pork with salt, garlic powder, and black pepper.
Let the seasoned pork sit for about 15 minutes.
Heat oil in a deep pan over medium-high heat.
Add the pork cubes, skin side down, to the hot oil.
Fry until the skin starts to puff up, about 10-15 minutes.
Turn the pork pieces occasionally for even cooking.
Remove the chicharrones from the oil once golden brown.
Drain excess oil on paper towels.
Allow to cool slightly before serving.
