Heat the oil over medium-high heat in a wok or large skillet. Add the garlic and ginger and stir fry for 30 seconds. Add the mushrooms and cook for 2 to 3 mins.
Add in the soy sauce, the bok choy and spring onions, and cook for a couple more minutes.
Reduce heat to medium-low and add the vegetable broth. Simmer until the bok choy is crisp-tender, 3 to 5 mins.
Stir in the sesame oil and the optional sesame seeds and remove from heat. Taste and add more soy sauce, if desired. Enjoy!
Recipe Note
