Lightly brush outside of cabbage wedges with oil, entirely coating.
Place carefully on a flat baking sheet. Leave space in between wedges so they can crisp.

Roast 15 minutes, then flip wedges, roast another 10 minutes or so, until outside pieces are crispy, & center is tender.
Serve with a fresh Lemon wedge.
