Preheat oven to 400℉. Line a large rimmed baking sheet with parchment paper.
Stem, then slice your cabbage head in half. Slice those halves in half and then again one more time half those in halves. You should have 8 equal size wedges.
In a small bowl, whisk together the olive oil, seasonings and garlic. Brush this mixture on all sides of the wedges. Roast for 20 minutes, then flip the wedges. Roast for another 15 minutes or until golden brown at the edges.
Tirokafteri (Spicy Greek Feta Dip):
