1. Slice the sweet potatoes into very thin rounds. Toss them with the remaining ingredients. Allow to marinate for half an hour. This will allow the sweet potato to soften slightly for easier skewering.
2. Preheat grill to high heat. Thread sweet potato rounds on the skewer by piercing carefully through the middle. Once skewered, wrap the sweet potato sticks in aluminum foil. This will allow steam to soften
the potato flesh without prior boiling.
3. Place the skewers on the top rack of the grates. Cook for 30 minutes, rotating the skewers halfway.
4. Unwrap and enjoy! Before serving,
sprinkle with a bit more salt.
