Pre-heat oven to 200°C/180°fan/gas mark 6.
Place ProZero, warm water, dried yeast and psyllium husk powder into a mixing bowl and stir until combined. Leave to rest for approximately 10 minutes.
Add Fate low protein all-purpose mix, olive oil, salt and mixed herbs into mixture and mix by hand until a dough forms. Knead for 2 minutes.
Leave dough to rise for 30 minutes in a warm place.
Dust hands with Fate low protein all-purpose mix and divide dough into two balls.
Roll one dough ball into a circle of 30cm long x 25cm wide
Cut into the shape of a large triangle and place onto a baking tray lined with greaseproof paper, keeping dough trimmings aside.
Using the dough trimmings make a 4x3cm rectangle and add to the bottom of the pizza to look like a base of a tree.
Brush the pizza base with olive oil and top with half of the passata sauce and half the grated Violife for pizza mozzarella flavour.
Use a small star cutter to cut a star out of a yellow pepper and place on the top of the triangle, then decorate with slices of pepper and red onion to look like tinsel.
Scatter half of the dried Italian herbs on top and bake in the oven for 20-25 minutes.
Repeat steps 7-11 with the second dough ball.
Remove from the oven and serve.
To make smaller pizzas, use large 13cm ‘Christmassy’ cookie cutters to cut shapes from the dough once it has been rolled out and decorate in the same way.
