Finely chop the onion and carrot.
Add cooking oil to a pan and stir-fry the pork neck first.
Once the pork is cooked, add the chopped onion and carrot and stir-fry together.
Add tofu and stir-fry gently so it doesn't break apart.
Add rice and stir-fry until all ingredients are well mixed.
Season with soy sauce, salt, and pepper.
Add green onions, stir-fry once more, and finish.
