In a large bowl, add ground pork, thin soy sauce, oyster sauce, sugar, black pepper, lemongrass, garlic, and Thai red peppers (optional). Mix well.

Begin to form small pork patties using about 2-3 tbsp of pork mixture. Place in an airtight container and allow to marinate for 2-3 hours (or overnight).

Prepare grill and lay patties on the hot grill. If using a food thermometer, make sure the internal heat of pork patties is at 145 degrees F. Grill until patties are golden brown with grilled marks.

Serve hot with noodles or rice.
