Peel the outer layer of cabbage off and then cut off the end. Start slicing 1” steaks of the cabbage and lay them out on a sheet pan or your counter. You want a thick enough cut to hold its form in the oven. Too thin, and it'll fall apart. Preheat oven to 375°F.
In a mixing bowl, combine salt, pepper, oregano, basil, garlic powder and olive oil and mix. Once mixed, using a pastry brush, paint the mixture on one side of the cabbage steaks and place them seasoned side down on a lined baking sheet or nonstick baking dish.
Next, add in half the parmesan cheese to seasoned olive oil and paint the mixture on the top side of the Cabbage Steaks. Place the sheet pan or baking dish in the oven and cook cabbage pizza for 30 minutes.
Remove cabbage pizza from the oven. Using Marinara or Sugar Free Pizza Sauce, top the cabbage with 1 ½ to 2 tablespoon of the sauce on every cabbage steak. Then, layer each steak with the remaining Mozzarella and Parmesan cheese and pepperonis. Bake the Cabbage Steaks for another 15 minutes to melt all the cheese and heat up the toppings.
Let it cool for 4-5 minutes before eating. For this pizza, you will need a fork and a knife. Enjoy!
