Add water gradually a little at a time and knead until you have a soft and smooth dough. Add the oil and knead again.
Cover and allow the atta dough to rest for at least 15 minutes.
In the meanwhile prepare the mashed potato filling. I like to add keep it quick and easy, by adding all the spices, coriander to the mashed potatoes and combine well.
Divide the dough into 6-8 dough balls. Pick one ball at a time and roll it into a small disc of 3-4 inch. Spread 1/8 a teaspoon of oil in the middle.
Place 2-3 tablespoons of the potato stuffing in the center. Starting right from the edge, begin pleating and seal the filling mixture with the dough.
Gently flatten the stuffed dough ball with your hands. Dust in the flour and roll the dough into 6-7 inches ciircle with a rolling pin. While rolling, apply equal pressure to the dough and you will have a circle paratha.
Heat the tawa to high temperature. Place the rolled paratha on the tawa and cook for at least 1 - 1 1/2 minute. Flip it around and drizzle oil on the half cooked side.
Flip again and drizzle oil on the other side and cook until the parathas have golden brown spots. Repeat the process for the remaining dough and filling.
