Ginger beef and bok choy

Place the oil in a large skillet and brown the steaks in it over medium-high heat.
When both sides are well-seared, add the pak choy, onion, garlic, and tomatoes.
In a bowl, stir the ginger, salt and pepper into the vinegar and add that mixture to the skillet, stirring to combine.
Cover the skillet, turn the heat to low, and let the whole thing simmer until liquids evaporates completely.
