Heat a pan and add 3 tablespoons of oil. Once the oil is hot add in 1/2 teaspoon of mustard seeds, 1/2 teaspoon of cumin seeds, 1 teaspoon of urad dal, 1 teaspoon of channa dal, 2 whole dried red chili, and 1/4 teaspoon of hing (asafoetida).
Allow the mustard seeds to splutter, then add 7 to 8 curry leaves, and 1 small slit green chili. Saute until the seeds splutter about 30 seconds.
Add the dried, desiccated grated coconut. Let it saute for about 2 minutes on low heat. Further, add the grated zucchini, 1 tsp salt, and cashews to the pan and cook until the zucchini becomes soft and all the water is absorbed. The salt added earlier will help draw out the water from the zucchini.
Once the water is fully absorbed, add in the rice and let it mix and saute for 3 to 4 minutes on medium heat. Stir intermittently, finally, add 2 tablespoons of chopped cilantro, roasted peanuts, and lemon juice. Mix well and turn off heat.
