Make the flatbread: Mix the flour, water, and oil in a bowl and knead for 5 minutes until it comes together. Place on a flat surface and roll into a 5 inch circle. Fold in half and roll it out again, repeating until it feels smooth, about 5 times. Split in thirds and form 3 balls of dough. Roll each out as thin as you can. On a hot grill pan or frying pan, dry cook the paratha for only about 2 or 3 minutes a side until it changes color and has some light browning. Wrap the paratha in a towel when they are done to keep them pliable.
