Since I can't have butter and I find olive oil & sweet potato a little odd, I was looking for new things to add. What I found was simple & delicious.
One medium-large sweet potato
Heaping teaspoon of coconut oil
I microwaved the potato for 6 minutes on high, then removed the skin & mashed it up. I added the coconut oil while still hot so it would melt, then sprinkled with cinnamon. The coconut oil gave it a fabulous creamy texture & the cinnamon made for a sweet treat.
