Combine all the ingredients in a mixing bowl. Add little water at a time and knead into a smooth, pliable dough (I think I added about ½cup water). Cover the dough with damp towel and set aside for 30 minutes.
Heat a tawa or griddle on medium flame.
Divide the dough into equal size balls. Roll out the dough into 5~6" round rotis. Sprinkle with dry flour as needed.
Place the roti on the hot tawa and cook until dark spots form, about 2 minutes. Brush with oil and flip and cook on the other side until cooked, another 1~2 minutes.
Repeat with rest of the dough.
