Personally I would far rather have cauliflower cheese.
I warm up an earthenware bowl whilst steaming some frozen cauliflower, just before the cauliflower is totally cooked I put it into the bowl, cover it with cream cheese, consider seasoning - herbs or paprika, then cover with grated Red Leicester cheese, put it back into the warm oven until the cheese is melted and slightly golden. Allow it to cool to a safe temperature before eating.
Some people like a layer of stronger cheese.
It is so simple and delicious.
