Blend together oats, coriander leaves, yoghurt, ginger, green chilies, water and all the dry spices.
Heat oil in a pan and temper with cumin seeds and asafoetida. Saute for a few seconds. Now pour the blended mix and simmer on a low flame.
Keep stirring at intervals till it gets thick to a desired consistency. Switch off the flame and transfer to a serving bowl.
Garnish with roasted oats and chili flakes (opt). Serve with any form of rice or Indian bread.
