  3. Place in oven and roast for about 20 minutes, or until soft.
  4. Place the cauliflower steaks on other prepared pan. Drizzle with two tablespoons olive oil and season with salt and pepper. Place cauliflower in oven and bake for about 30 minutes, rotating halfway through the cooking time until tender and golden brown.
