Kale has become so trendy, I want to dislike it just on principle.  Plus it’s a super-bitter leafy green that usually has to be taken in small doses and paired with some other strong flavor to make it remotely palatable.  My friends with Vitamix blenders all got on a green smoothie kick using kale.  When the best thing you can say about a vegetable is “You can’t even taste it!” then you know something is wrong.  However, my die-hard healthy friends helped me out with some decent options.
