Cauliflower is an amazing little tool, especially if you like the taste. The more you cook it, however, the more bland it gets and better blends in. I LOVE it in macaroni and cheese. Now, I've only done with with the Homestyle cheddar flavor packet that Kraft makes (bought 2 on sale), and prepared as directed, but added 2 cups of well cooked, broken into pieces, cauliflower bits. The second time I made it, I eliminated the butter from the "flavor packet" that you mix with with (skim) milk before adding the prepared cheese packet, then the macaroni and cauliflower, topped with the seasoned bread crumbs and baked, and I swear, both my daughter and I who love cauliflower could not taste it in the dish. It really blended in and the casserole was absolutely delicious. Trust me, you don't miss the butter either and the skim milk works fine.
I had been looking for faux rice pudding recipes made with cauliflower and they exist, with mixed reviews. For a blandish recipe, it does seem to me like ti would make a tasty rice pudding alternative.
It has been used as a rice substitute, and no so successfully as a mashed potatotes substitute, but it can't hurt to try, if you like cauliflower.
I plan on using it to replace rice in stuffed peppers, and I can't imagine it won't be delicious.
And by the way, it was the most guiltless dish of mac and cheese i ever ate!
You can also, when making traditional style lasagna, add chopped spinach and parsley mixed throughout the riccotta cheese for extra flavor, and a tiny bit of chopped garlic and onion too.
Jessica Seinfeld (Jerry's wife) actually wrote a book on this similar subject, trying to incorporate veg into kid's dishes. Not that anyone should run out and buy it, but its worth a Googleing.
On Amazon.com there is a link on this page to one of her recipes for brownies incorporating carrot and spinach purees.
