tomato puree??? pizza

I really want to try the smash pizza-any reveiws on it?

Also would you use tomato puree on it or something else (is tomato puree free?)

Tomato puree is half a syn per level tbsp but you could use passata which is syn free. Personally I'm not a fan of this mock pizza but others seem to like it. I would rather use a pitta bread of wholemeal bread mix to get a proper pizza base.
