Cauliflower or Broccoli Gratin

This is an outline. I don't really follow a recipe when I make this.

Small head of cauliflower cooked until almost tender
Salt, pepper
Chicken broth
Cheddar Cheese or Parmesan
Bread Crumbs
Parmesan cheese

Make a roux with butter and flour. Add a little minced garlic.

Add  chicken broth and/or cream. Cook until sauce is thick and add some cheddar or Parmesan cheese.

Stir in the cauliflower.  Pour into a casserole dish.

Saute some fresh bread crumbs in a little butter seasoned with garlic and more Parmesan cheese and sprinkle on top of the cauliflower.  Bake in a 350 oven until hot.
