Remove all the cabbage leaves and cut each leaf in half. Romanian cabbage rolls are traditionally smaller than the Polish cabbage rolls, so that's why I recommend cutting each leaf in half, otherwise you can use the entire leave for one roll.
Chop the onions and fry them in the oil until tender. Add rice and cook for another minute. Add onion and rice mixture to ground pork and add salt, pepper, dill and parsley and mix well with your hands. Now it's time to assemble the rolls.
