In a large bowl, sift together flour and salt. Add oil and mix in with a fork until flour is crumbly. Mix in water until the dough pulls together. Turn dough out onto a lightly floured surface and knead until smooth and elastic, about 8 minutes. Cover and set aside for 45 minutes.
Knead dough again until smooth; divide into six equal parts. Form each part into a round. Roll out each round as thinly as possible; dust with flour to keep from sticking.
Heat a tawa. Spread roti over pan and cook. Roti will cook in 40 to 50 seconds. Tiny black spots will appear when it is finished. Fold roti and serve hot.
