First, cut the edges of the bread and push it with a rolling pin. If you don't have a push stick or are in trouble, you can put a sheet of plastic on it and press it with your hands.

Place ingredients one after the other on a well-pressed bread. If you want to make it into a wrapping shape when you roll it up, you can cut the ends a little bit like the one below.

Roll it in two and wrap it up.

When you just roll the top one, the bottom one is when you cut the end slightly.

If you cut it with a knife wrapped in plastic wrap, it looks like this. If you untie the wrap, it becomes a bite-sized ham and cheese roll sandwich.

I put it neatly on the plate. Even if you do it on a busy morning. It's a good snack for kids. You can feel the taste of the ingredients in the chewy texture. It's the peak of a picnic these days, so I think it'd be good to give it to you simply when you don't have anything to pack.
