Combine pork belly with the soy sauce, lemon, salt, ground black pepper, garlic and mix well. Marinade the pork belly for at least 3 hours.
In a bowl, pour the pork belly marinade. Add banana catsup and cooking oil. Stir well. (This will be the basting sauce)
Grill the pork belly while basting the top part of the pork after flipping it over.
Serve hot with spiced vinegar or toyomansi. Share and Enjoy!
