I LOVE cauliflower and I have a really easy recipe that uses only three ingredients.
Boil as much cauliflower as your family can eat. When it's almost done, remove it from the boiling water and place in an oven proof dish. Sprinkle (or dump on) it with your favorite cheese. (I've used Parmesan, cheddar and mozzarella), and then sprinkle (or dump on) seasoned (or unseasoned--depending on your preference) breadcrumbs. Bake at 360 until the cheese melts and the breadcrumbs are golden brown (10-15 minutes).
Yum!
