Kale is something we know is good for us.  But the biggest challenge is always how do I make kale and make it taste good.  We'll so far sautéed kale is my favorite.  This one is coming in a close second.  I was disappointed in how the sweet potato came out because I overcooked it. They ended up mushy.

Just watch the time you cook the onion and sweet potato before adding the kale.  It takes a good 7-14 more minutes to cook down the kale because each batch you add takes about 7 minutes to cook down. Make sure the sweet potato's are still someone andante when you add the kale.
