Delicious! Since this was a weeknight meal, I made the sauce ahead of time, marinated the steak in the fridge during the day (in soy, rice vinegar, olive oil, minced garlic and ginger), and once the rice was done cooking in the rice cooker, I threw the chopped bok choy in with it on the warm setting for a bit to soften. I served with a cucumber and pepper salad.
