They served us this at work the other day. I brought home the recipe. DEE-LISH!
No quantities on the ingredients. Use as much or as little as you desire.
Kale leaves, julienned, and massaged with lemon juice and honey. Cover and refrigerate at least two hours (according to the recipe), and up to four days (which is what I did, and it was fine.)
Toss well, and drizzle with some superb balsamic vinegar*.
* My addition. I used this. It is truly swoon-worthy.
