Break idlis in bite size pieces and set aside (I make three to four shallow vertical cuts and break it using hands. Then I break the horizontal pieces into three to four pieces. I keep the look rustic by avoiding the knife to cut the idli)

Place a frying pan on high heat and add two teaspoon of oil. Tip in the broken idli pieces and fry till the idli turns golden in color. Remove the idli pieces on a plate and set aside.
(Frying idlis is purely an optional step. You can skip this if you wish to. I fry it for the reason that it helps idli pieces hold their shape better when the tempering is added to it)

Place the pan again on heat and add ghee and add peanuts and cashews. Fry on medium low heat, stirring continuously, till the cashews turn golden. Using a spoon, carefully remove the peanuts and cashews on a plate lined with absorbent sheet.

On medium heat, in the remaining ghee, add the mustard seeds and broken dry red chilies. Once the mustard seeds begin to crackle, add the chana dal. Fry for ten seconds and add the urad dal as well. Fry till the dal just begins to turn golden.

Now tip in the chopped green chili and sliced onions (add more ghee if required) and fry till the onions turn translucent. Add the curry leaves and green peas. Stir and cook for half a more minute.

Lower the heat to minimum and add salt, turmeric powder, amchur and sambar powder. Give a stir and then sprinkle some water, (a tablespoon or two), to avoid the masala from burning. Stir everything well.

Add the broken idli pieces and gently mix and stir everything well to ensure that all pieces are nicely coated with spices. Add a little more water, may be a sprinkle, only if required.

Once done, switch off the heat, cover the pot and allow the contents to sit for 10 – 15 minutes for the flavors and spices to get absorbed by the idli pieces. Lastly, add the peanuts and cashews and mix everything again. Serve hot or at room temperature in individual bowls.
