Combine green onions, lemongrass, salt, pepper, and sugar into a large bowl. Mix together until it becomes a thick paste. Add fish sauce, brandy and chili flakes, and stir well.
Coat each pork chop with the seasoning. Refrigerate for at least a couple hours (up to 24 hours).
Grill at approximately 400 degrees F, about 7 to 8 minutes on each side.
