Add the drained lentils and the rest of the dal ingredients in a saucepan over medium heat. Partially cover and cook until the lentils are cooked to your preference. 13-17 minutes. Taste and adjust the salt and flavor. Add ½ cup of water or coconut milk, if needed for preferred consistency, and mix in. You can also add the chopped tomato and cilantro at this point and mix them in.
Heat a skillet over medium heat. Add the oil. Once the oil is hot increase the heat to medium-high and add the green chilies. Cook until the green chilies are slightly brown and blistered. Add the garlic and toss for a few seconds then add the cumin seeds, toss those for a few seconds and add the peanuts. Add a generous pinch of salt and mix really well and switch off the heat.
Keep stirring for the next few seconds to cook the garlic and peanuts in the remnant pan heat, until they get golden.
Once the mixture has slightly cooled down, transfer it to a mortar and pestle and then press and mix to break down all the peanuts until you achieve a coarse mixture. You can also use a small food processor and process it until you achieve a coarse mixture.
When the dal is ready, switch off the heat, then top the dal with spoonfuls of thecha and just swirl the thecha into the dal but do not mix in entirely. Garnish with some cilantro and lemon juice and serve with rice, flatbread, or roti.
