Kale instead of parsley in tabbouleah?

[Retrograde]

10. I use Italian flat parsley for tabbouleah

and it tastes- and looks - nothing like kale. They are from two different plant families.

I like kale, but for me it's a winter vegetable - some varieties may be good in a cold salad, but I wouldn't put a curly kale in a tabbouleah - I'd save that for a greens and beans dish, where the kale gets cooked long and slow.
