Total Time: 25 minutes
Servings: 4


  • 2 pounds  flank or flatiron steak, cut into 1/4 inch thick slices
  • 5 tablespoons  soy sauce
  • 2 tablespoons  rice wine vinegar
  • 4 teaspoons  cornstarch
  • 2 tablespoons  vegetable oil
  • 4 cloves garlic, minced
  • 1/2 pound  green beans, trimmed
  • 1 pound  mushrooms, sliced
  • 1 baby bok choy
  • 1 cup  water
  • 3 tablespoons  fish sauce
  • 1/2 teaspoon  freshly ground pepper


  • To make the meat extra tender and flavorful, it’s important to marinate it first. In a medium bowl, stir together the cornstarch, 2 tablespoons of the soy sauce, and the rice wine until the cornstarch is dissolved. Add the beef and toss to coat. Let stand for at least 10 minutes. While the steak is marinating this is the perfect time to prep the rest of the ingredients.
  • Heat a wok or large skillet over high heat until a bead of water sizzles and evaporates on contact. Add the oil and swirl to coat the bottom. Add the beef and spread it out in a single layer. Allow it to sear untouched for 1 minute, then stir-fry for another 1 to 2 minutes until the pink is mostly gone. Transfer to a plate and set aside.
  • In the same wok or skillet, add the garlic and stir-fry very briefly (about 20 seconds), just until aromatic. Add the green beans and stir-fry for another 1 minute. Add the water and immediately cover with a lid. Allow the green beans to steam for 3 to 4 minutes, or until they are crisp-tender and the water has evaporated.
  • Return the beef to the pan and also add the mushrooms and bok choy. Add the fish sauce, the remaining 3 tablespoons of soy sauce, and the black pepper. Stir so that everything is well coated, then turn off the heat. Transfer to a plate and serve. 


  • If you don’t have a wok, this will turn out just as delicious in a skillet. However, if you want to buy a wok there are plenty of places where you can buy an inexpensive wok. Cost Plus and Target are just a couple of places.
  • I find using a wok when cooking Asian dishes makes it even easier to bring the dish together. Because you’re cooking at such a high temperature, when you use a skillet the oil tends to splatter and your skillet will most likely need a good soak overnight. In a wok, there is less tendency to splatter, and clean up can be easier, too.
  • Either way, you’re going to have a delicious, easy and healthy dinner!
