What Is This Weird Green Thingy?

What has Mel given me? It's a very strange, looking thingy! All green with bobbly bits. I think it is quite beautiful really. It is my mission to find out what it is. What do you think it is? 

Mel helped me research it on her computer. It's called a Romanesco broccoli. That doesn't look like the broccoli that I've had before. I do like broccoli. It is like eating tiny trees! Ha ha! Apparently this type of broccoli has more flavour. What can I make with it? Any ideas?
