Take off the leaves at the stem of cauliflower. Cut off stem without breaking the head of cauliflower apart. Wash and place the entire cauliflower head in a cast iron pan. Drizzle and rub olive oil all over the cauliflower. Sprinkle with salt and spices of your choice. (I used my fave blend spice grinder) Cover pan with tinfoil and bake at 375 for 30 minutes. Take the tinfoil off. Add some butter and sprinkle with grated Parmesan cheese and top with shredded mozzarella and bake Until cheese is melted and golden. About ten to fifteen mins
