Rinse the okra and pat dry. Set aside for now.
Press the sauté button, add oil and allow it to heat up for a minute. Once the oil is hot, add cumin seeds to the pot and once they turn brown, add the onions and stir-fry for 3-4 minutes or until they soften a bit.
Remove the onions from the pot and place on a plate, set aside.
Put the okra into the pot and stir-fry for 2 minutes, then add potatoes and green chili and fry for another 2 minutes.
Add the spices, stir, then add onion masala and water and mix well. Place the tomatoes on top.
Secure the lid, close the pressure valve and cook at high pressure for 1 minute.
Naturally release pressure for 5 minutes, then open the valve to release any remaining pressure.
Add the cubed onions back to the pot, stir, then garnish with cilantro and serve.
