This is now on our menu for this coming week with a couple of minor changes. The first being in going to use a cauliflower based dough (from a diet point of view that will be better for me, I'm too fond of carbohydrates sadly) and because I want to try it, I'm going to make a vegan mozzarella.
I think if I made it again I'd use some cheese too. Hope it works. I've never been convinced by cauliflower pizza vases though... but I know you've made them before.
