Cut pork and kimchi into bite-sized pieces.
Heat cooking oil in a pan and stir-fry the pork.
When the pork is cooked, add the kimchi and stir-fry together.
Add gochujang (Korean chili paste), soy sauce, sugar, and minced garlic to season.
Stir-fry over medium heat so the seasoning is well absorbed.
Add green onion and sesame oil, stir-fry once more, and finish.
