1. Wash the baby bok choy thoroughly under cold running water. Trim the ends and cut them in half lengthwise.
2. Heat up the vegetable oil in a large skillet or wok over medium-high heat.
3. Gently add the minced garlic and grated ginger to the hot oil. Sauté for about 30 seconds or until fragrant.
4. Add the baby bok choy to the skillet. Stir-fry for 2-3 minutes, tossing the bok choy to coat it evenly with the garlic and ginger.
5. In a small bowl, mix soy sauce, oyster sauce (if using), and sesame oil. Pour the sauce over the bok choy.
6. Continue stir-frying for an additional 2-3 minutes or until the bok choy is tender-crisp. Be careful not to overcook; you want it to remain slightly crunchy.
7. Season with salt and pepper to taste. Adjust the seasoning if needed.
8. Transfer the baby bok choy to a serving platter. Garnish with sesame seeds if desired.
9. Serve immediately as a side dish with rice or your favorite main course.
