Place whole sweet potatoes in a pot and cover them with water. Add a little salt. Bring to a boil.
Cook for about 10 minutes (or until you can put a fork in it but still has a bit of resistance -don’t want it to be mushy, but needs to be somewhat soft-ish)
Drain and let cool. Slice sweet potato in half, then cut into wedges.
Coat the wedges with a little avocado oil and then add your spices. Grill each side for 3-5 minutes or until grill marks appear.
