If you want to make the soya chunks instantly, bring 3 cups of water to a boil. Add the soya chunks and leave them in the water till they soften for about 2-3 mintes. Strain the soya chunks in a large strainer and run under cold water for a minute. Squeeze the soya chunks to remove extra liquid.
Start the pressure cooker in sauté mode and let it heat. Add oil and whole spices. Sauté for 30 seconds.
When the cumin seeds change color, add onions, ginger and garlic. Sauté for about 5 minutes until the onions become golden brown while stirring frequently.
Add tomato puree and spices. Stir and saute for 2 minutes.
Add the soya chunks and green peas. Saute for about 3 minutes.
Add 1.5 cups water and stir well. Deglaze the pot by scraping to make sure nothing is stuck to the bottom of the pot. Press cancel and close lid with vent in sealing position.
Change the instant pot setting to manual or pressure cook mode at high pressure for 3 mins. After the instant pot beeps, quick release the pressure manually. Open the pot. Garnish with cilantro and enjoy Soya Curry with roti, naan or rice.
