Grilled Sweet Potatoes

Ingredients

4 medium sweet potatoes (about 3 pounds), scrubbed well
1 tsp coarse sea salt
1 tsp cumin
1 tsp paprika
1/2 tsp cinnamon
1/2 tsp chipotle powder
2 tbsp apple cider vinegar
1/4 cup extra virgin olive oil

Directions

Cover potatoes with cold, salted water in a large pot, then bring to a boil.  Simmer until slightly resistant when pierced with a sharp knife, 5-7 minutes. Drain well. When cool, slice potatoes lengthwise.  Mix together salt, spices and apple cider vinegar, add oil in a slow stream.  Brush this mixture on sweet potatoes.  Grill potatoes on a lightly oiled grill rack over medium heat, until grill marks appear and potatoes are cooked through, about 15 minutes.
