Directions

1. In a small bowl, whisk together vinegar, soy sauce, and sesame oil. Set aside.
   
2. In a large skillet with a lid, bring 1 cup water and ginger to a boil. Add the bok choy; reduce to a simmer. Cover and cook until leaves are vibrant green and stems are fork-tender, 3 to 5 minutes. Drain well; discard ginger.
   
3. Transfer boy choy to a serving platter; drizzle with the vinegar-soy mixture, and serve immediately.
