Marinate: In a bowl, combine soy sauce, vinegar, garlic, bay leaves, peppercorns, and sugar. Marinate the meat for at least 30 minutes.
Cook: In a large pan, heat oil over medium heat. Brown the meat pieces on all sides.
Simmer: Add the marinade mixture and water. Bring to a boil, then lower the heat and simmer for 30-40 minutes, until the meat is tender and the sauce thickens.
Serve: Pair with steamed rice and enjoy the savory, tangy goodness.
