Anyone wild about watercress?

[multigraincracker]

Saw a thing about it on line and how great it was for health, so thought I'd give it a try. First I asked my friend that knows about this kind of stuff and he just said it was bitter.
I toasted up a couple of slice of multigrain bread, of course, and made a smoked salmon sandwich with some watercress and mustard. YUM.
I found the stems were pretty bitter, so I discarded the bigger stems.
