Wash the bok choy user cold water and chop it up, separating the stems from the leaves.
Heat olive oil in a large non stick sauce pan and toss in the garlic and ginger. Cook for just a about a minute or until fragrant. Add bok choy stems, soy sauce and a splash of water and cook for 5 minutes.
Once the stems are becoming tender, toss in the bok choy leaves and cook until they have wilted down.
Season with salt and pepper and finish with a sprinkle of toasted sesame seeds. Enjoy!
