I used just regular green cabbage. Here's the recipe: (Note what we discussed above about using olive oil.)
-Cabbage cut into wedges and cores trimmed. (I used 4 wedges or one half cabbage.)
-Brush w/ olive oil whisked w/ lemon juice (both sides) (I used 1 tbsp. oil w. 2 tbsp. lemon juice.)
-Sea salt and fresh ground black pepper (sprinkled on both sides)
Roast at 450 degrees on a pan greased w/ olive oil or spray for 15 min. Carefully turn (try to keep wedges intact) and roast for another 10-15 min.
I also HIGHLY recommend lining the pan w/ foil for easy clean up.
