I was not clever enough (or quick enough) to write this list myself, so I am sending you to a fellow ("sister" really) Michigan Lady Food Blogger who just wrote an article with this title for her blog called The Local Cook. Check it out - all her recipes sounds great.
In addition, I love the idea of a cooking class just on greens, what they are, which are which, how to prepare and use various ones. I would suggest also including instruction on how to freeze kale and other hardy greens for future use during the weeks (and weeks) when you are overwhelmed with the amount of various fresh greens in your CSA box. Yes, I've been there myself, so much so that is when I first started feeding kale to my dog (yep, she loves kale, too!). I have never given it away to friends (or worse, composted it) because I am pretty vigilant about freezing our extra greens. Here is the link to my post about freezing kale.
Enjoy reading another bloggers growing enthusiasm for kale!
