In a large bowl, combine the pork cubes, garlic, lemongrass, fish sauce, brown sugar, and vegetable oil. Season with salt and pepper, then stir to combine.
Thread the pork cubes onto the skewers, making sure to leave some space between each one. Place the skewers on a plate, cover with plastic wrap, and refrigerate for at least 1 hour.
Heat an outdoor grill or grill pan to medium-high heat. Place the skewers onto the grill and cook, turning occasionally, until the pork is cooked through and lightly charred, about 10 minutes.
Serve the skewers with steamed rice or noodles, if desired.
