Spaghetti with Tuna, Lemon and Rocket

…or Spaghetti with Tuna, Lemon and Arugula for any American readers.

This one comes from Nigellissima: Instant Italian Inspiration by Nigella Lawson, and is one of my standby recipes for when I want something quick and easy.

The only thing that needs cooking is the spaghetti, everything else gets mixed in a bowl and then tossed with the spaghetti at the end. Unfortunately for us though our bag of rocket had gone off by the time we came to cook it, hence the lack of greenery in the final picture.
