Crisp watercress salad

Author Notes

I have a feeling I may have given this one away slightly with the title - I couldn't think of anything snappier - ah well. I love watercress as a salad leaf - it's got a delicious peppery flavor. Just the other day I was whinging to my husband about how it's hard to find in US supermarkets (my perennial moan always starts with "in the UK you can get ... *insert any ingredient / service / some superior british product* ... everywhere" - cue surreptitious eye rolling from my American husband).
Anyway, I've just discovered I was totally wrong on this particular one, I was just looking in the wrong section, watercress is kept in the fresh herbs section, not the salad section like it is in the UK.
I know, I know, the ingredients are very far from seasonal - but I'm officially fed up of root veggies - roll on spring please! —cooklynveg
