In a large mixing bowl, combine whole wheat flour, flaxseed powder, ajwain, cumin powder, and salt.
Gradually add warm water and knead into a soft smooth dough.
Cover and let the dough rest for 10 minutes.
Divide dough into equal portions and roll into thin rotis using dry flour.
Heat a tawa and cook each roti until brown spots appear on both sides.
Brush lightly with ghee if desired and serve warm.
