Add chopped garlic (generous amount), onions, green chili and saute till translucent.
Next, add the diced tomatoes and saute till the tomatoes turn tender.
Then add hing and other ground spices and salt to it. Toss to mix all. Hing adds a nice strong flavor to these lentil recipes indeed.
Then add chopped methi or fenugreek leaves. Saute for a minute.
Next, add washed lentils to the cooker or the large pot.
Add water to it as needed. After that close the lid and cook for 2 - 3 whistles in a manual pressure cooker.
Or simmer in the pot for 10 - 15 minutes or till the lentils are cooked completely. Keep the flame low to medium and cover while simmering. You can also use an Instant Pot and cook for 5 minutes on high pressure.
Method II
Heat oil in a pan.
Once the oil is hot, add cumin seeds and hing. Let the seeds crackle completely.
Add minced garlic, green chilies, and chopped onions, and saute till translucent.
Add tomatoes followed by salt. When tomatoes are tender, add the ground spices. Stir them nicely.
Once the masala is cooked and starts releasing oil on the sides, add chopped leaves.
Cook on low flame for 5 - 6 minutes or till the leaves are cooked soft and tender.
Next, add the cooked dal or leftover dal. Stir nicely mixing everything.
Add ¼ cup water if required and then simmer on low heat for another 3 - 5 minutes.
Additional Tempering
You can also add an additional tempering or tadka to the dal in the end.
For additional tadka, heat a small pan. Add oil or clarified butter.
Once the oil is hot, add some more minced garlic, and cumin seeds and let them crackle and the garlic starts to change color.
Turn off the heat and to the pan add red chili powder or paprika.
Mix once and then pour in the tempering into the methi dal. This tadka is optional though.
In the end, add finely chopped coriander leaves. Serve hot.
