In a small bowl add yeast, sugar and 1/4 cup of the warm water. Stir and allow to sit for 5 minutes until frothy. In a large mixing bowl add flour, salt and 2 tablespoons of olive oil, mix. Add yeast mixture, mix and add a little bit of the warm water until a dough like consistency has formed. The dough should not be sticky. Roll in a bowl, cover outside with more olive oil, place in a bowl and cover with a few kitchen towels to keep warm. Leave for an hour until doubled in size.
