In a large mixing bowl, whisk together the flour, salt, and olive oil until the oil is mixed in and there are little crumbles of dough.
In a separate bowl, stir the sugar into the warm water until dissolved. Then stir in the yeast. Let it rise until bubbly, about 5-10 minutes.
Pour the yeast mixture into the dry ingredients and mix until a dough forms. Use your hands to finish mixing the wet and dry ingredients until a thick, pliable dough forms.
Knead the dough until soft, about 10 minutes. Then transfer the dough to a lightly greased bowl. Cover with a damp towel and let it rise for at least one hour or until doubled in size.
Once doubled, tip the dough onto a floured surface. Divide the dough into two evenly sized balls. Roll into balls, then cover and place in the fridge for 30 minutes. Use this time to make the sauce and toppings.
