In a mixing bowl, combine soy sauce, honey, ginger, and garlic. Add chicken thighs and marinate for at least 15 minutes.

Heat a skillet over medium heat and cook the marinated chicken for about 20 minutes, or until fully cooked.

Steam the bao buns according to package instructions until warm.

Assemble the bao by placing cooked chicken in the bun and topping with cucumber, cilantro, and scallions.
