To begin making the Gawar ki Sabzi, first heat oil in a pressure cooker over medium heat.
Add the ajwain seeds and allow it to crackle.
Once it crackles, add the onion, ginger and garlic and saute until the onions become tender and pinkish brown.
At this stage, add the tomatoes, turmeric powder, red chilli powder, coriander powder and saute until the tomatoes become mushy.
Once the tomatoes become mushy, add the cut guar/ cluster beans, salt to taste and 1/4 cup of water.
Pressure cook for 3 to 4 whistles and turn off the heat. Release the pressure immediately to retain the bright green colour of the gawar ki sabzi.
Once opened, give the Gawar Ki Sabzi a stir and check the salt and spices and adjust accordingly.
Transfer the Gawar Ki Sabzi to a serving bowl and serve hot.
