Combine oil, salt, pepper, garlic powder, and chili powder. Mix well until the powders are diluted in oil.
Rub the oil mixture in each piece of pork chop.
Place the pork chop in a covered container. Refrigerate for at least 3 hours for the flavors to be absorbed.
Heat the grill. Using medium heat, grill each side of the pork chop for about 8 to 12 minutes depending on the thickness of the cut. Baste with remaining oil mixture.
Transfer to a serving plate. Serve with sliced green mangoes, tomatoes, salted eggs, and shrimp paste.
