Preheat the oven to 400F. 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 portions and flatten each into a half-moon shape large enough for a cabbage slice. Place a cabbage slice on top of each Parmesan mound and spread out. Drizzle the tops with a little more oil and seasoning.
Bake for 16-19 minutes, until all the edges of the cheese are browned.
Remove from the oven, let cool 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.
