Wash and soak dry peas for about 5-6 hours in warm water or overnight.
Once soaked enough, add them into the pressure cooker. Peel and cube the potato and add it with the dry peas.
Add turmeric powder, asafetida (hing), green chilies, and salt, and pressure cook for 3-4 whistles. Once cooked, mash it a little bit with a potato masher and keep it aside.
In a deep pan, heat oil, add cumin seeds, hing, ginger, green chilies, cumin-coriander powder, fennel powder, turmeric, and chili powder, and roast for a minute on low flame. Then add 1/2 cup of water, rock salt, and let it boil.
Now, add the cooked peas and potato mixture to the boiling water, mix well, add more water if required, and let the curry boil. Then, cook it on low flame for about 5 minutes.
Next, add green chutney, tamarind water, and chopped coriander, and mix it well. Keep it aside.

Spread all three chutneys as per your taste, then top with chopped onion, tomato, chopped green chiles, and coriander leaves over the chutneys.
Squeeze lime juice, sprinkle some sev, pomegranate arils, and sprinkle chaat masala, chili powder, rock salt, over the mixture, and serve immediately. Enjoy!
