Soak the roasted moong dal in water for 15-20 minutes. Heat oil in a pan and temper with the panch phoron. After it stops spluttering, add the asafoetida.
Then add the bori and fry till golden colour. Now add the onions, garlic and green chilies. Saute till light brown. Add the greens, drained dal, salt, turmeric powder and coriander-cumin powder.
Stir fry on a low flame for 8-10 minutes. When done, add the kasundi and give it a mix. Serve with either plain steamed rice or chapattis.
Note-
In place of kasundi, you can grind 1 tsp. mustard seeds, salt, turmeric powder and 1 green chili.
