There is nothing like a sweet potato, baked, with butter and cinnamon.
So easy and so good for you (well, the potato is, not sure about the butter!)
Poke a few holes in them.
Place on the grill. They have to bake about an hour on the grill, depending on the heat and how big the potatoes are!
If you are just going to microwave, depending on the size, it will probably take between 8-12 minutes, for 2. This also depends on the size of the potatoes and the strength of the microwave.
Unwrap, slice open, slap some butter and cinnamon on the top and gobble up!
