"Cauliflower Au Gratin"
One of my bf's other favorites. Actually it's the only way he eats it lol.
1 Cup of bechamel sauce (white sauce, not sure if you call it bechamel in english also. I usually make my own but you can buy packages to make it at the grocery store)
Steam the Cauliflower until tender. Place in a oven proof casserole. Add the bechamel sauce and then top with cheddar. Place in the oven at 375F until cheese is melted. You can also do this sliced peeled potatoes which is quite good.
