Soak the black eyed peas in abundant water for 4 hours or overnight so they are all submerged. When you are ready to cook, drain the water.
Start the Pressure Cooker in sauté mode and heat it. Add oil and cumin seeds. Then add the diced green chili pepper. Once the cumin seeds start to splutter, add the onions, ginger and garlic. Let this cook for 3-4 mins.
Add the tomatoes and spices to the instant pot and cook for another 3 mins.
Add the drained black eyed peas and water to the instant pot. Stir well. Press Cancel and close the lid with vent in sealing position.
After the instant pot beeps, let the pressure release naturally. Stir in the lime juice. Garnish with cilantro and serve with roti/rice.
