1Preheat oven to 200°C if fan-forced (220°C conventional).
2In a small bowl, dissolve yeast and sugar in 1 cup of warm water.
3Mix together flours, olive oil and salt. Stir in the yeast mixture and mix well to form a dough.
4Turn out onto a floured surface and knead for 1-2 minutes. Leave to rest for 5 minutes.
5Divide dough into two and roll each portion of dough on a floured surface to around 1 cm in thickness. Transfer to a large tray or pizza stone.
6Spread pizza sauce over base using the back of a spoon, leaving about 2 cm around edge. Top with onion, tomato, eggplant, mushrooms, olives and sprinkle over cheese (or try our stretchy, gooey, melty mozzarella!). Bake for 15 minutes or until crust is golden brown.
