Cut pork neck, potato, and konjac into bite-sized pieces.
Soak the potatoes in cold water to remove starch.
Heat oil in a pan and stir-fry the pork neck.
When the pork is cooked, add potatoes and konjac and stir-fry together.
Add soy sauce, sugar, minced garlic, and water, and bring to a boil.
Cover with a lid and simmer over medium low heat until the ingredients are cooked through.
Finish by adding green onion and sesame oil at the end.
