Raw Kale Chips are superwonderful. Dried in the dehydrator. If you try it, you might consider making Chocolate ones! HolyYum
Though the last few times I had Kale in salads I had indigestion. I think even a little bit of raw Spinach freaks out my tummy nowadays!
Someone in here mentioned Kale affecting their throat...that could be a thyroid issue. I read that Brassicas can irritate the thyroid. It would seem that cooking, and fermentation can both solve this.
I have some Kale growing in my garden right now, I think it is Dwarf Russian, its starting to get quite big and beautiful. I am also going to plant some Ornamental Kale... you know, this stuff.

I think I will use all of my Kale in soups and in fermented Krauts... KaleKraut!
"It is considered to be closer to wild cabbage than most domesticated forms." - Wikipedia on Kale... interesting
