To make this dal tadka, first soak chana dal and masoor dal in water for 30 minutes and then turn on the Instant Pot to Saute Mode. Add ghee to the pan. If you are vegan, then add any cooking oil instead. Once its hot, temper mustard seeds. Once they begin to crackle, add cumin seeds, finely chopped green chillies, minced ginger and chopped garlic. Using a wooden spoon, saute till the garlic turns golden and then add chopped cilantro to the pan and saute for 30 seconds. Now this is a trick I learnt from my friend. Always add part of chopped cilantro at this point in oil in any recipe. Frying cilantro in oil brings out a great flavor. Then add chopped onion and salt. Continue to saute till the onions turn soft and translucent and then add chopped tomatoes. Cook till they turn soft and mushy. I always like to add some green leafy vegetables to my dal as it's a great way to sneak in healthy veggies. Here I added beet leaves which if unavailable, you can add spinach or kale.
