Preheat the oven to 400 degrees.
Wash and clean the cabbage. Pull off any outer leaves that look damaged and then slice to 1 1/2 inch thick. You should get 5-6 steaks from one cabbage.
Combine the olive oil, onion powder, garlic powder, garlic salt and paprika. Brush over the tops of the cabbage steaks. You only have to add this to one side.
Add the cabbage steaks to the oven for 20 minutes.
While the cabbage cooks, make the pancetta in a pan on the stove. It will take about 3 minutes. Watch for it to turn a deeper red color and then remove it from the burner.
Remove from the oven, add a little salt and pepper if you like and then add the parmesan on the tops of the cabbage.
Broil for 1-2 minutes. I always go 2 so the cheese is melted and a little crispy on top.
Add on the pancetta and parsley and enjoy!
