Add poha to the microwave safe dish and roast it in the microwave on high for a minute. Mix well and heat the poha again for a minute. Set aside.
In a wok or kadhai, heat oil on medium heat.
Add mustard seeds and when they start to splutter add kadipatta leaves and green chilly.
Fry them for 20 seconds and then add roasted chana dal, peanuts, and cashews (if using).
Stir them in and add poha, turmeric powder, and salt. Fry them for another 5-6 minutes on medium to low heat till the mixture is well combined.
Let the mixture completely cool before storing in an airtight container.
NOTE: I have used roasted chana dal, peanut, and cashews. To roast them you can choose to use a little oil or do it without oil. Roast them on medium heat; check for doneness and let it cool completely before storing them in an airtight container
