We're totally on a cauliflower kick over here. My son absolutely loves it so I've been trying out some different things. I did the (suddenly so popular) cauliflower pizza crust but I need work on it some more. I think it could be much better so more on that later.
I've also done it steamed with carrots and then seasoned with butter, salt, and pepper. It's really good, but kind of boring. But, hey, if my kid will eat it then I love it.
