use Smash as a base (sounds crazy & is a bit of a faff but it actually works)
I used roasted onion flavour which is 1syn for the whole packet but if you use plain it will be syn free
make it up with a little less water than the packet says
spray some fry light on a pizza tray/baking tray then spread mash mixture as thinly as possible (if you use a pizza tray there is the perfect amount to cover the whole 12" tray)
shove into the oven for 6-10 mins until it starts crisping up a bit
remove & allow to cool
carefully turn it over by placing something on top of it & turning upside down then slide back into tray
shove back in the oven for another few mins (I was just playing this by ear so not a precise method)
remove from oven & allow to cool
spread with passatta then top with whatever free stuff you like (I used ham, mushrooms, onions, sliced tomato, jalapenoes & chilli flakes)
use 42g Mozzarella as your HEA & sprinkle with italian herbs
**you could always use a bit more cheese as long as you count it as syns**
shove back in the oven for roughly 10-15 mins (depending how much topping you used) then scoff the lot & enjoy every mouthful!
