Use atta flour (whole wheat, made from hard wheat). Add water to flour until it's tender and smooth, not too much water. Roll out into thin circles like chapati. Make a cut from the center to an edge, then fold over into a 60 degree triangle (so it'll be 6 layers). It'll be kind of a cone shape, so kinda squash that open, flatten, and roll out. Cook on a hot dry pan. Put oil on one side, then flip so it cooks on both sides.
