Cook the cous cous (add to boiling water and simmer until soft - it only takes about 8-9 minutes).
Whilst the cous cous is cooking, make the vinaigrette by adding all the ingredients to a jar and shaking well. Chop the cucumber into small chunks and finely chop the herbs.
Once the cous cous is ready, drain and rinse under cold water and then add to a large serving bowl with all the other ingredients, pour over the dressing and mix and serve.
