Take amaranth seed flour in a mixing bowl, add whole-wheat flour, sesame seeds, green chillies, coriander leaves, ginger, yogurt, salt and turmeric powder and mix well. Add sufficient water and knead into a semi-soft dough. Add 2 tbsps oil and knead till it is well incorporated. Cover with a damp muslin cloth and set aside for 10-15 minutes.
Divide the dough into equal portions and shape into balls. Dust the work-top with whole-wheat flour and roll each ball into a thepla,
Heat a non-stick tawa, place each thepla on it, and cook till the underside is almost done. Flip, drizzle a little oil and flip again. Drizzle a little oil on the other side too and cook, turning side till both sides are light brown and crisp.
Keep the Theplas on serving plates and serve hot with green chutney.
