Soak the bamboo skewer in water at least 1/2 hour (while you marinate the pork), to prevent them from burning while on the grill.
Slice the pork into thin long strips, a quarter of an inch thick. If you are planning on using the skewer, inch wide strips are better. If you are grilling the pork on the grill without the skewers, a bigger piece will help it from falling into the coals.
Press or mince the garlic. Mix all ingredients together and marinate for half an hour or even over night.
If you are using the skewers, thread a skewer through the pork. Grill the pork until it is well done.
