How to arrange high school students' breakfast scientifically and reasonably?

I am a student myself, and I really have no appetite for the same food every morning. Bread is too oily and milk is disgusting. Personally, I think parents had better cook breakfast in different ways. Porridge, egg custard and fruit juice are all good choices, which are nutritious and easy to accept. You can also eat some sausages and eggs as a supplement. As for the staple food, you can eat steamed cakes, which are more delicious, or you can eat something else. In short, don't always eat one.
