Steam cauliflower in the microwave for about four minutes, until almost cooked (a little crunchy still), or boil for 5 minutes.
Preheat to 350 F
In a mixing bowl combine cheese, miracle whip, curry and soup together. Stir in the cauliflower and toss to coat. Make sure every cauliflower gets some sauce on it.
Spread in a greased 13x9 casserole dish. Top with breadcrumbs. My favorite is Panko crumbs - they stay crunchy.
