Mix soy sauce, oyster sauce, honey, mustard, ground pepper and Chinese five spices in a small bowl. Set aside.
Heat cooking oil in a pan to a medium setting and wait until the oil starts to heat up. Add the pigs in blankets to the pan and cook them until they are golden brown all around. Take the pigs in blankets out of the pan and set aside.
In the same pan used for the pigs in blankets, fry the red onions until soft, then add the pak choi and the sauce made earlier. Add star anise and pomegranate, stir until all combined.
Put the pigs in blankets back in the pan and mix well with all the vegetables and sauce.
To serve, sprinkle a little bit of ground black pepper. You can enjoy this dish on its own or have it with rice or noodles.
