I borrowed this from somewhere on the internet, but the ingredient list was not in order and the instructions were unnecessarily difficult to follow, hence I'm adding here! This is delicious and easy to make low-carb! Notes: 1) if using the pressure cooker, the chicken can be fresh or frozen. Frozen will just take longer to get to pressure. 2) this will make a lot of sauce. don't hesitate to add more spinach, more chicken, etc. 3) you will need to do a CONTROLLED quick release on the pressure cooker to avoid making a huge mess in your kitchen. I learned this the hard way!
