Roast Cauliflower

I know this is almost too simple to even need a recipe, but it is something I  had never thought to do, and I did, and I tried it, and it is delicious.
Clean all of the green from a head of cauliflower. Slice it and layer the slices in a large pan (like a lasagna pan). Sprinkle with salt and pepper, dot with butter. Sprinkle on some grated Parmesan cheese. Bake at 400* for about 1/2 hour-40 mins or till tender. That's it. SO good! I suppose you could experiment with other cheeses, too, but so far I've only made it this way.
