Soak the dals in hot water along with the red chillies and a pinch of turmeric for 60-90 mins .
Meanwhile chop the veggies fine and steam them for 10 mins till 90% done but not mushy.
Let all the water evaporate from the veggies , but let it remain moist.
If using Capsicum in place of any veggie, simply saute for 2-3 mins, no need to steam (see Tips / Notes for more details)
Drain the dals, grind them with red chillies, asafoetida and turmeric to a semi-coarse paste.
Add chopped coriander leaves(if using), salt and mix well.
Place this ground mixture in Idli moulds or a flat plate and steam for 15-17 minutes or till a skewer comes clean (I used an idli steamer for 14 minutes)
Cool completely.
Once completely cooled, simply mash up the cooked dal into a consistency of bread crumbs (if your dal is well steamed, the crumbs can be made in a matter of minutes.
If there’s some moisture left, crumble them thoroughly, and saute in a tsp of oil for 5-6 mins before proceeding to the next step.
In a pan, make the tempering of the mustard, curry leaves and chillies.
Add the steamed veggies and sauté in the oil for 4 mins on low. Once done, add the dal crumbs and toss for 2-3 mins taking care not to mash them up.
The stir-fry is quite dry in consistency yet holds a bit of moisture
Serve immediately with rice, morkozhambu or any Vathakuzhambu and a dollop of ghee for a satiating meal.
