Cut two thin slices off a cucumber with a slicer or peeler.
Cut the ham to the same width as the cucumber slices. Roll them up together.
Story Behind this Recipe
To fill gaps in a bento....
Don't try to poke through these with toothpicks or bento picks to secure them. They seem to hold up better in a bento box on their own. The cucumber is very thin, so be careful not to rip it when you're rolling it up.
