I've seen all the hype - so I thought I'd give it a go myself!
Verdict... tastes OK but you need a pretty good garlicy tomato sauce to mask the fact that it is califlower not dough.
Would I eat it again? Yes definitely - as long as I didn't have to make it. The process, and the cooking times were both loooooooooong, especially considering Pizza is usually the easy option for dinner with friends.
