Cut the pork and various vegetables into appropriate sizes.
Heat cooking oil in a pan and stir-fry the pork.
When the pork is halfway cooked, add the vegetables and spicy green chili peppers, and stir-fry together.
Add seasonings such as gochujang (Korean chili paste), chili powder, soy sauce, and minced garlic, then stir-fry so the flavors are well absorbed.
Once the ingredients are cooked through and the seasoning is evenly coated, transfer to a plate and serve.
