Combine yeast, warm water and sugar in a small bowl, cover with plastic wrap and allow to stand in a warm place for 10 minutes or until small bubbles appear on the surface.
In a large bowl, combine sifted plain flour and salt. Pour in oil and yeast mixture and stir until a dough has formed. Turn dough onto a lightly floured surface and knead for approximately 5 minutes or until dough is smooth and elastic.
Place dough in a large greased bowl. Cover with plastic wrap and let rise in a warm place for 40 minutes or until dough is doubled in size.
Knead the dough again and roll out two pizza bases. Spread with Leggo’s Tomato Paste and top with cheeses.
Bake in a preheated oven at 200°C for 15-20 minutes or until cheese has melted and base is golden around the edges. Serve immediately.
