I love baked sweet potatoes, but they take so long to make. Plus, you have to heat up your oven and thereby heat up your house. Not what you are looking for when it is hot outside. So I started to roast the sweet potatoes in coals of the grill. You need a charcoal grill for this method, but it is worth it. The high heat sears the outside and makes the sweet potatoes come out super sweet and tender in around 45 minutes.
