Asparagus with Orange Dressing

Asparagus has many kind of vitamins and I like to cook Asparagus in Japanese way, Western way.

This is Asparagus Salad with orange dressing.  Boil Asparagus then soak in the cold water so that the colour stay bright green.  Squeeze 2 oranges into the pan and bring to boil.  It becomes thick then off.  Add chopped onions and mustard and orange zest.  Grate pecorino cheese on top.
