Slice the cabbage and green onion thinly. Cut the pork belly into bite-sized pieces.
Add the pork belly to a pan and cook over medium heat until golden and crispy.
Once the fat is rendered out, add the green onion and stir-fry, then add the cabbage and cook until softened.
Add soy sauce, sugar, and pepper. Stir-fry everything so the ingredients are evenly seasoned.
Place the stir-fried mixture over rice and sprinkle with sesame seeds to finish.
