Peel leaves, core and wash a head of cauliflower. Place on sheet of foil. Butter lightly. Cover with about 1 cup grated Parmesan cheese. Cover tightly with the foil. Bake about 1 hour at 350 degrees. Near end of baking unwrap and check for doneness and add more cheese if desired at this time. Re-wrap and finish baking. Serve on platter, pull back foil and will come apart easily.
