Wash and dry the sweet potato. Don't peel it. Pierce it in a few places with a fork.
Place the potato on a paper towel and microwave it on high for 3 minutes. Turn it to the other side and microwave for 2 more minutes, or until fork-tender.
Allow the potato to rest for 2 minutes before serving.
I like to simply slice the cooked potato and enjoy its natural sweetness - I don't even sprinkle it with salt, as I find the saltiness detracts from its natural flavor. But obviously, you can cut it in half, sprinkle it with salt and pepper, and top it with a little butter.
Toppings such as butter are optional and were not included in the nutrition info. There's no need to peel the potato. You can simply wash it well, then microwave it with the skin on. Sweet potato skin is edible, so it's up to you if you want to remove it before eating or not. I like to leave it on.
