Cut the pork and vegetables into bite-sized pieces.
Heat cooking oil in a pan and stir-fry the pork.
When the surface of the meat is cooked, add onion, green onion, chili pepper, and stir-fry together.
Add chili powder, soy sauce, minced garlic, and other seasonings and stir-fry until the sauce is well absorbed.
Once the seasoning is well absorbed and all ingredients are cooked, it's ready to serve.
