Wash and peel the carrot.  Using a julienne peeler, cut the carrot into thin straw-like strips.  If you don't have a julienne peeler, use a sharp knife to cut the carrot into really thin strips or grate the carrot instead.

Pile the carrot into cupcake cases (I use brightly coloured silicone cases) or small ramekins, shaping into a rough nest with your fingers.

Cut egg shapes from the cucumber slices using an oval shaped mini bento cutter.  Pop a few into each nest and serve.
