    this sounds really good! how many servings is this recipe? im thinking to double it and maybe hand blend? any thoughts?

    • Skinny Ms.  August 21, 2012

      Carol, Definitely double the recipe. About 4-5 servings of 1 cup each.

  2. Tammy Tidwell Jones  August 23, 2012

    Are these sweet potatoes or yams? The coloring looks like yams

  3. Tammy Tidwell Jones  August 23, 2012

    I was wondering the same thing :/

  4. Skinny Ms.  August 25, 2012

    Tammy, Sweet potatoes.

  5. Tammy Tidwell Jones  August 29, 2012

    Made this the other day. I won't make it again.

    • Skinny Ms.  August 29, 2012

    what was wrong with it?

  8. Tammy Tidwell Jones  September 15, 2012

    The taste just wasn't right for me, my hubby&3 kids. But my Mother loved it lol

    • Skinny Ms.  September 16, 2012

      Tammy, Glad your mom loved it. 🙂

    Well, I've been excited to make this since I first pinned it on Pinterest months ago. I fixed it today and my husband and I almost died. It. Was. So. Spicy!! We seriously choked it down sharing a huge glass of milk to help with the burn. My husband actually asked me if I was trying to kill us! haha. But seriously, I won't fix this again. 🙁

    • Skinny Ms.  May 5, 2013

      Mel, This dish is a little on the spicy side…some like it hot, others prefer mild. The amount of spice can easily be tweaked according to taste. Also the red pepper can be completely eliminated. 🙂

    I made this yesterday, and it was delicious!! Based on previous comments, however, I doubled the recipe and omitted the red pepper flakes and sea salt. In their place, I added about a half teaspoon of mild Harissa and the kale about an hour before it was done. The kale still had a little crunch to it. I'm from the South, i.e. simply wilted doesn't get it :-)! I will definitely make it again.

    • Skinny Ms.  June 15, 2013

      Laverne, lol…I’m also from the south. Here we typically cook greens until they’re falling a part! I’ve learned to adapt because of the health benefits of not over cooking. 🙂

    A co-worker brought this in for a potluck lunch today, and it was delicious!

    • SkinnyMs  February 13, 2014

      Jesse, Great! Thanks for letting us know. 🙂

    This was great – I have made it twice, although I did notice that the recipe yielded less than I expected – about 4 1-1/4 cup servings instead of 6, but adding more vegetable stock seemed to help the second time around. LOVE the heat. Used 1 regular sweet potato and one purple one to add some more color to the dish. Great for meal prep all week.

  13. gettingskinny22  November 20, 2014

    Instead of red pepper flakes, whats a good seasoning alternative to give it a savory flavor?

    • SkinnyMs  November 20, 2014

      Gettingskinny22, Paprika or smoked paprika is a nice alternative. You can use more since it's not spicy.

  14. Gail  January 7, 2016

    I made it today. Yes, it is spicy. I put organic sour cream (just a bit) in the center, to have a cooling sensation present. Great for cold weather.

  15. Liz A.  July 24, 2019

    I’m excited to try this! I find it so funny how people have such varying degrees with their taste buds. Not sure how 1/4 t. red pepper can possibly overpower anything. Wimps! 😂
