• You could eat an entire kilogram of watercress for a mere 110 calories – better still, a study recently found that eating 3 ounces daily increases levels of the cancer – fighting antioxidants lutein and betacarotene. 
• OK, so that’s a lot of watercress, but it does mean  it’s worth eating it as often as possible. 
• I’m more entranced by its wild taste – dense, delicious and, it seems to me, the precise flavor I imagine when I think of green.

      generous handful of watercress, washed and tough stems removed
      1 orange, peeled and segmented
      10 blanched almonds, roughly chopped

   
      For the dressing:

      1 tsp Dijon mustard
      2 tsps red wine vinegar
      ½ tsp honey
      2 tsps rapeseed oil
      2 tsps poppy seeds
      salt and pepper

      Combine the salad ingredients. Drizzle with dressing and serve.
