Preheat your grill to medium-high.
Bring a pot of water to boil on the stovetop. Blanch the wedges 3 to 4 minutes and drain.
In a bowl, combine all the ingredients for the spicy seasoning.
Place the wedges in a big bowl, drip the oil onto them, and mix well, making sure all the wedges are coated with olive oil.
Add the spicy seasoning and mix well again, making sure everything is well covered. You might not need to use all of the seasoning.
Grill the wedges for approximately 10 minutes, or until nicely charred and soft, turning them once in a while.
