Cut the cabbage in half and then quarters, slice out the core to discard (or put into the compost), and then cut the cabbage quarters into 1 to 1 1/2 inch wedges.
Place the wedges onto a Silpat or parchment paper lined baking sheet and brush with avocado oil.
Sprinkle sea salt and pepper and put about a tablespoon or so of freshly grated parmesan cheese on each wedge and then roast in a 425 degree oven for 25 minutes.
