In a pressure cooker, add the peeled and cleaned yams along with the pinch of turmeric powder and water and mix. Pressure cook for about 3-4 whistles. This might change depending on the type of pressure cooker you have.
Once the yams are cooked, take them out of the water and let them cool down.
Next, chop them into bite sized pieces.
For the sabzi, heat oil in a pan. Add the mustard seeds, fenugreek seeds, and carom seeds. Saute.
Next, add a pinch of hing and saute.
Add the green chilies, turmeric powder, and red chili powder. Saute.
Next, add the sliced onions and the prepared boiled yam. Mix and saute. Cook for 2 minutes.
Add the chopped broad beans next and mix. Saute and cook for 5-6 minutes or until the broad beans become soft and cooked.
Add the coriander and cumin powder next and mix well. Saute and cook for another 2 minutes.
Once the mixture starts to dry, add the water and let it cook for a few minutes until the water dries up.
Garnish with chopped coriander leaves and serve hot with rice and curry or Indian breads of your choice.
