Much to my surprise, I received good feedback for this very humble dish. Can't be easier: cut up a head of cauliflower (1.5 cm thick) and spread them out single layer in a baking pan. Salt and pepper to taste, add enough milk to barely cover the cauliflower. Top generously with grated cheese (any flavourful ones that you like, I use french cheese "Comte"). Bake covered at 190 degree Celsius for 50 minutes. Serve hot.
