Pre-heat oven to 180 degrees celsius fan-forced.
In a small mixing bowl, add half of the besan flour and combine it with the yoghurt using a spoon, until it is a pasty mixture.
1 cup besan flour, 2/3 cup greek yoghurt
Then combine in the rest of the chickpea flour until the dough can be formed into a ball. It should be sticky. Be careful not to over-mix or the dough may go sloppy. If you cannot pick up your dough, add a little more flour.
lay a 30cm piece of baking paper on a flat bench and sprinkle with besan flour. Coat your hands with besan flour and place the dough on the baking paper. knead dough for a minute, it should start to dry out and become more like dough.
Coat a rolling pin with besan flour and roll out dough until it is 1/2cm thick (or just coat your hands and use them to flatten out the dough).
Put on desired pizza toppings. I used tomato passata sauce, cheese, olives, mushrooms, capsicum, rocket and prosciutto. Then cook in the oven for 15-20 minutes or until the base is completely cooked through. If the base is overcooked it will be dry and if it is undercooked it won't taste great.
