Add flour, salt, oil in a mixing bowl and rub together with your hands..Gradually add in water and form into a soft dough.
Apply few drops of oil over the dough and cover it with a wet cloth and let it rest for 15-20 mins.
Now divide the dough into equal portions and start rolling into a circle.
Apply some oil over the top and sprinkle some flour on it. Fold the paratha in half and apply some more oil and sprinkle with flour..Fold into triangles and roll the triangle into a paratha keeping its shape as a triangle.
Heat a tawa on high heat and put the paratha on it. Cook on one side for about 30 sec or till you see no dough on top. Flip it over and cook on other side too..Cook on both sides till it gets cooked.
No need to use oil for cooking paratha. The paratha will puff up like a balloon..Put this in an insulated container.
