Wash the duck meat and bok choy thoroughly, and cut them into bite-sized pieces.
Heat cooking oil in a pan and stir-fry the duck meat over medium heat.
Once the duck is partially cooked, add minced garlic and continue to stir-fry.
Add the bok choy and stir-fry together.
Season with soy sauce, salt, and pepper.
Continue to stir-fry until the bok choy softens, then serve on a plate.
