It doesn't take a lot to make delicious sweet potatoes. They're great baked, roasted and, of course, mashed sweet potatoes are hard to resist, too. But have you ever tried grilled sweet potato slices? It's a great twist that's worth trying.

Before you cook them, these sweet potato slices get a quick blanch in hot water and then hit the grill to cook up hot and fast. The blanching helps the potatoes cook faster, and helps to ensure that the insides stay creamy and the outsides get nicely charred. The best part is that most of the preparation can be done in advance. Just keep the potatoes covered in the fridge until you're ready to grill them.

So keep the lid open for this part of the cooking.
