Tomatillos(also called green tomatoes) are cheap and available easily in any grocery store. I love its tangy flavor. This kootu can be made quickly and had with rice or roti.
To pressure cook:
4-5 small tomatillos(husk should be peeled)
1 green chilli
Moong dhal-1/3 cup
Shredded/frozen coconut-2 tbsp
Turmeric powder-a pinch
Mustard seeds-1/2 tsp
Curry leaves-a few
Pressure cook all of the above ingredients for 2 whistles.
Do the seasoning and simmer the mixture for 2 minutes.
Serve with rice or roti.
