Set you Instant pot to sauté mode.
Add ghee and let it the ghee become hot.
Once hot, add the cumin seeds. They should crackle once you add them to the hot ghee.
Add the onions, garlic and ginger and sauté for 2-3 minutes, until the onions are translucent.
Add all the spices to the pot- cumin powder, turmeric powder, garam masala, red chili powder, salt and sauté for another 2 minutes.
Add the diced tomatoes and let them sweat for 2-3 minutes.
Add the spinach one handful at a time and let them wilt down.
Now add the red lentils and 2 cups of water.
Cover the Instant pot. Set it on high power for 10 minutes. If using a regular pot, bring the dal to a boil and then cover with a lid and let it simmer for 15 minutes, until the lentils soften.
Once cooked, add the lemon juice, mint leaves and cilantro.
Serve as a soup or with warm rice.
