From The Complete Superfoods Cookbook by Michael van Straten
Serving 4
1 large bunch watercress, stalks removed
2 white onions, finely sliced
2 tbsp extra-virgin olive oil
1 tbsp walnut oil
Method
Thoroughly wash the watercress – even if it's ‘ready-washed'.
Dry the watercress and put in a bowl, laying the onion slices on top.
Drizzle with both oils – and enjoy!
As Michael van Straten says in his latest book, "There's more than just visual appeal to this simple but powerful immunity boosting salad. Watercress belongs to the same valuable plant family as cabbages, broccoli and Brussels sprouts. It contains some iodine, lots of potassium and the strong mustard oil known as benzyl, which is an effective antibiotic".
