Combine all the ingredients except the beef and cooking oil.

Coat evenly each piece of meat with the marinade. In a plastic container with cover, pile beef pieces one on top of the other.

Cover and keep refrigerated overnight or until ready to cook. Heat oil in a wok at high heat, fry marinated beef in batches for 3-5 minutes each side or until color changes to brown and edges start to caramelize.

Serve hot with fried rice and egg.
