Cut off the bottom of the bok choy and cut in the middle lengthwise. Cut the stems into 1-inch wide strips.
In a wok or large skillet, sauté the garlic and ginger in the olive oil about 1 minute over medium heat. Add the bok choy and sauté over high heat for about 3 minutes. Add water and continue to cook for another 4-5 minutes stirring occasionally. Season with soy sauce, hoisin sauce, a handful of chopped almonds and pepper and give it a last stir.
Soak the bok choy in a large bowl with fresh, cold water to remove all the sand and dirt hidden in the root part of the bok choy. I rinsed mine three times.
