It worked.
I rolled out the dough pretty thin, and used tomato reduction, diced pepper, onion, garlic, olives, artichoke, mushrooms and mozzarella (there's a not too bad grated vegan type) and pesto.
(I understand the purists would consider this too many toppings at once) .
Folded it over sealed the edges and baked for 20 mins or so - four big ones in total.
Very nice, and was appreciated.
But of course, it doesn't have the same crunchy bubbled cheesey topping as an open pizza.
Still an interesting experiment for the novelty value.
And a nice bottle of Spanish* red to go with.
* Sorry i prefer Spanish over Italian..
Thanks for all the tips and info.
