Breakfast, in many cultures around the world, often came about as a result of what foods were left from foods they had the day before. Cold meats often served for breakfast in parts of Europe; soups, rice, cold fish, in Asian regions. Traditional breakfasts mostly came about from the need to use food prudently.
The lesson here should be, rather than try to imitate breakfast from other cultures, we should forget about what constitutes a breakfast dish. Assuming we are eating healthy and tasty foods for our other meals, we simply find creative ways to eat leftovers the next morning.
