Fill a medium sized saucepan ¾ full of water and add a large pinch of salt.  Bring to the boil.  When boiling add the pasta and boil,uncovered, for 10 - 12 minutes until tender but with a little ‘bite’ in the middle.

While the pasta is cooking make the dressing: put the oil, vinegar, mustard and mayonnaise into a mixing bowl and whisk together with a fork.

Drain the pasta in a colander over the sink and tip into the bowl with the dressing. Leave to cool.  Put the kidney beans into a sieve and rinse in cold water.

Cut the roots and most of the green part off the spring onion and remove the outside layer.  Chop into small pieces.  De seed and chop the pepper. Cut the cucumber into small cubes. Cut the cherry tomatoes in half.  Set a few aside for decoration.
