Add oil to a heavy bottom pot. Once hot, add cumin seeds and asafetida. Let the cumin seeds start to splutter.
Now add finely chopped tomatoes, garlic and green chilies.
Once the garlic starts to turn golden brown and tomatoes are mushy, add turmeric and salt. Mix well.
Now add chopped potatoes. Mix again. Cover and cook. Stir them every now and then, until they are cooked.
Once the potatoes are fork tender, add finely chopped methi leaves.
Then add red chili powder, and cumin-coriander powder. Mix everything well. Cook until methi is cooked. It should take about 2-3 minutes.
Serve hot with piping hot Rotis, or parathas
