Prepare the Bok Choy: Rinse the bok choy thoroughly to remove any dirt between the leaves. Chop it into bite-sized pieces and set aside.

Cook the Ground Meat: In a large skillet or wok, heat 1 tablespoon of vegetable oil over medium-high heat. Add the ground meat and cook, breaking it apart with a spoon until browned and fully cooked (about 5-7 minutes). Remove the cooked meat from the pan and set aside.

Sauté Aromatics: In the same skillet, add another tablespoon of oil if needed. Add the chopped onion, garlic, and ginger. Sauté for 2-3 minutes until fragrant and the onion is softened.

Add the Bok Choy: Add the chopped bok choy to the pan, stirring well to coat it in the oil and aromatics. Cook for 3-4 minutes until the bok choy is tender but still slightly crisp.

Stir in Sauces: Return the cooked ground meat to the pan. Stir in the soy sauce, oyster sauce (if using), hoisin sauce (if using), rice vinegar, and sugar. Mix everything together and cook for another 2-3 minutes, allowing the flavors to meld.

Finish and Serve: If you want to add a bit of heat, sprinkle red pepper flakes on top. Drizzle with sesame oil for extra flavor. Garnish with fresh cilantro or green onions, if desired. Serve immediately over steamed rice or noodles for a complete meal.
