Combine yeast, sugar and water in a measuring cup and set aside for 5~10 minutes or until the mixture gets foamy.
In a medium mixing bowl, combine flour (s), salt and oil. Slowly add the yeast mixture and knead into a smooth and soft dough.
Transfer the dough into a greased bowl, cover and set aside to rise for 1½hour or until doubled in volume.
Sprinkle flour on a baking sheet and keep ready.
Gently deflate the dough and roll it out into ¼" thick rectangle on a lightly floured surface.
Using a medium sized round cutter (I used a 3¼" round cutter), cut the dough and place them on the prepared baking sheet. Cover the baking sheet and set aside to rise for 1 hour.
At the end of the rising time, preheat the oven to 350°F. Brush the discs with oil and sprinkle with more flour.
Bake for 10~15 minutes. These bread are supposed to be white, so make sure that they don't over-bake and change color.
