Fresh baby kale is so much nicer in salads compared to regular kale. Last time we were in L.A, we saw it everywhere!  I personally haven't seen many places stock it yet, but I'm sure it won't be long till you can get it at your local grocer. So good luck with the hunt, it'll be worth it! And if not, you can replace it with regular kale. I'd give it a quick blanch, just to soften and bring the lovely green colour out in it. As for the sprouts, if you're not a fan just use another kind from the cabbage family. The recipe is from Sprouted Kitchen. Enjoy!
