Soak tamarind paste in 1/2 cup hot water. Dice beans, carrots and green chili finely. Rinse red lentils and millet once, drain and keep aside. If you using rice, rinse 3-4 times until the water runs clear (this will ensure the rice is not starchy).
To a pressure cooker, add oil. Add cumin seeds and roast for a minute.
Add green chillies, ginger paste and saute for a minute.
Add garam masala, turmeric, chili powder & coriander powder. Mix well and add tamarind juice (drain them of the pulp). Mix until the spices are cooked.
Add frozen grated coconut and mix until combined. Add water if the mixture is too dry.
Mix well and add red lentils, vegetables, and lastly millet or rice.
Add remaining water, salt and mix well. Pressure cook for 5 whistles (about 10 minutes).
When it's about to be done, temper your spices. Add vegan butter to a small pan.
Add mustard seeds, hing, turmeric, curry leaves, red chillies and cashews. Roast them until the cashews are light brown.
Take them off the heat immediately and pour over the cooked stew. Mix well.
Garnish with more roasted cashews and chopped coriander. Enjoy!
