Cucumber-stuffed chikuwa (chikuwa kyuri)
Chikuwa, the tube-shaped grilled fish cake sold in every Japanese supermarket, gets the simplest treatment of all in children's bento: a stick of crisp cucumber pushed through the hole and the tube sliced into rounds, so each piece looks like a little green-eyed wheel. It is cold, crunchy and gently savoury, ready in five minutes on a busy morning, and good as an after-school nibble too. Chikuwa is ready to eat; it contains fish and usually wheat and egg white, so check the label. Chef's tip: trim the cucumber stick to fit snugly; too fat and the chikuwa splits.
