In a bowl, mix the hoisin sauce, soy sauce, oyster sauce, honey, Chinese five-spice powder, minced garlic, and minced ginger to create the marinade for the pork.
Season the thinly sliced pork shoulder with salt and pepper, then coat it with the marinade. Allow it to marinate for at least 30 minutes.
Preheat the grill to medium-high heat.
Grill the marinated pork slices for about 2-3 minutes on each side, until they are cooked through and have a nice char.
For the buns, warm them according to the package instructions if using store-bought ones.
Slice the warm buns open and fill each with a few slices of the grilled pork.
Top the pork with sliced cucumbers, fresh cilantro leaves, and a sprinkle of sesame seeds.
Drizzle with extra soy sauce or hoisin sauce if desired.
