This thuvayal is easy to make, very healthy and tastes great with rice. It can be prepared with coriander leaves or curry leaves or pudina/mint leaves or a mix of all the 3 greens. Here I have given the recipe using pudina leaves/mint leaves.
Heat a tsp of oil in a kadai, add urad dal, channa dal, tur dal, red chillies, whole black pepper and asafoetida. Saute until dal turns golden brown. Remove from heat.
Then add pudina leaves and sauté in the heat of the pan.
Once it cools, grind it along with tamarind, salt and a little water.
This thuvaiyal tastes delicious when mixed with hot steamed rice and a tsp of ghee/sesame seed oil.
It can be used as an accompaniment for chappati and dosa also.
Note - I personally use 3-4 dried gooseberry pieces instead of tamarind as gooseberries are rich source of vitamin C.
You can also use a mix of greens (mint leaves, curry leaves and coriander leaves) and make this thogayal.
