Everything about this recipe is awesome. Go for whole milk ricotta.
I just discovered this recipe and I've got to say, I never would have imagined how good Kale and Sweet Potatoes go together! I added a touch of cinnamon (my fave) as well and this was just a wonderfully tasty meal. I'm going through peri-menopause and trying to eat healthier, and your site is very helpful. I also recently watched a great documentary called "Hot Flash Havoc" that really answered a lot of my questions, if anyone's interested you can check it out here: http://bit.ly/11XQcWS
