Mix together wheat flour and gram flour in a bowl. Add red chilli powder, coriander powder, garam masala powder, dried mango powder, turmeric powder and salt. Add sufficient water and knead into dough.
Heat a non stick tawa. Divide the dough into equal portions and shape them into balls. Dust each ball with a little dry flour and roll into a roti.
Apply ½ tsp ghee over the roti, sprinkle some chopped green chilles, a pinch of carom seeds, a pinch of cumin seeds, some red chilli powder, some dried mango powder and some dry flour.
Fold each roti into half. Apply ½ tsp ghee and sprinkle some dry flour. Fold once again to form a triangle. Dust with a little dry flour and roll out into a parantha.
Place each parantha on the hot tawa and cook, turning sides. Apply a little ghee on both sides and cook till evenly golden.
Transfer onto a serving plate and serve hot.
