I would take the whole cooked steak and cut when ready to serve will not dry out unless transporting in a liquid.. I would use some bell peppers, onions, tomatillos cut up and heated slightly in a pan just before serving and would then add the sliced mea to reheat. Don't forget the tortillas. garnish with cilantro (if you like the flavor) and some sour cream, gucomole and shredded cheese. Beans refried and Mexican rice are a nice side.
