This is one of the best recipes from a perspective of how much time it take, Vs how nourished you’ll be.  The chicken is fall off the bone tender and will be ready when you come home from work.  Then you’ll take 15 minutes to whip up some sweet potato mash and you’re good to go.

  11. Serve two thighs each with half the sweet potato mash each.  Make sure you get the juices and all of the onions from the slow cooker.


  • I use tallow to brown the meat since it will give a wonderful colour and flavour, but you can use any other animal fat, or a little olive oil and butter.
