Preheat the oven to 400. Line a sheet pan with parchment paper (or use a NONSTICK sheet pan)
Add the Parmesan to the sheet pan, then add the seasoning and the oil. Mix together to make a paste. Divide into 5-6 equal sized portions and flatten to create a a half moon shape (large enough for each cabbage slice). Place the cabbage slices on top of the Parmesan mixtures. Drizzle the tops with a little more oil and seasoning.
Place the cabbage in the oven for 16-19 minutes, until all the edges of the cheese are brown.
Remove the cabbage from the oven, allow it to cool for a couple of minutes, drain the excess oil, then carefully lift the edges of the cheese and use a spatula to flip the slices over. Bake for another 10 minutes.
Top with the parsley and pepitas.
