Wash and then soak the pigeon peas in water for about 30 minutes.
Add the soaked pigeon peas, 1/2 teaspoon turmeric powder, roughly chopped tomato, and 3 cups of water in a pressure cooker and cook till the pigeon peas are soft and mushy.
While the pigeon peas are cooking, take a pan and heat the oil. Add mustard seeds/cumin seeds( whatever is your preference) and asafoetida.
Once the seeds crackle, add green chillies and red chillies.
Then add curry leaves and onions and fry till the onions become translucent.
Add vegetables of your choice. I had some zucchini, carrots, and moringa leaves in my home, so I used those.
Add salt, cover with a lid and let the vegetables cook to about 80%.
Add the vegetables to the pressure cooker where pigeon peas have been cooked.
Add Tamarind juice, sambar powder, and jaggery. Taste and adjust salt.
Close the lid and let everything cook together for 5 minutes more.
Remove from heat. Garnish with Coriander and serve with steamed rice.
