Preheat oven to 425 degrees.
Prepare a large baking sheet with non stick spray, or liner.
Take head of cabbage and peal off the first layer if they are loose. Cut off bottom end where steam was.
Slice entire head up into 1/2 inch thick steaks. (layers will be falling off while you do this. Thats ok. Just try and keep them together as well as you can.)
Place each steak flat down on baking sheet. Drizzle each steak with olive oil. Only the side that's facing up.
Sprinkle each steak with spices (salt, pepper, onion powder, oregano, roasted garlic & herb blend) about one pinch or a couple shakes of each herb for each steak.
Cook in preheated oven for about 25-30 minutes. When the outer layers of the cabbage start to crisp up and almost burn, they are done.
Immediately after they are out of the oven, drizzle honey dijon mustard on top of each steak. To make this easy, I poured my mustard inside a ziplock baggy, cut a corner tip off the bag and squeezed it out.
Enjoy!
