First peel and cut the lauki into cubes. Wash it and set aside. Also you can cut your ginger, green chili and have it ready. I used canned tomato puree, if you are using fresh tomatoes then puree them too.
Start your instant pot on a SAUTE mode. Once the screen show HOT, add oil and cumin seeds. Let the seeds splutter. Now add asafoetida, dry chili pepper. After a few secs, add ginger and green chilies. Saute for an additional few seconds and add tomato puree. Saute until the tomato doesn't have a raw smell.
Add cut lauki and along with salt, turmeric, red chili powder. Mix it well. Put the lid and SEAL it. Now press, MANUAL and time set to 25 mins. Once it is done you can leave it for another 5-6 mins and release the pressure. Using the potato masher, mash it a little bit. Add garam masala to it at this time.
Garnish it with cilantro. Enjoy it hot with boiled rice or roti.
