Wash and peel the sweet potatoes and cut into thick wedges as shown in the picture. Add the butter, maple and season generously with salt and pepper. Wrap with a double layer of tin foil.
Cook the sweet potatoes over medium heat for about 25-30 minutes or until soft when poked with a knife.
Remove the sweet potatoes from the tin foil and save the butter that's left over to finish the sweet potatoes later. Grill over high heat until nicely coloured on both sides (about 5-10 minutes).
Brush the finished sweet potatoes with the leftover butter/maple and sprinkle generously with sesame seeds. Share on a big plate. Enjoy
It's a good idea to keep an eye on these potatoes while grilling. If the tin foil wrap is punctured, the butter will drain out onto the grill and may cause a flare up. Be careful when moving the tin foil package and try not to puncture it.
