Easy to make,but a yummy,tangy side dish that goes well with IdlI,dosa and rotis also! My mom makes with moong dal in this, but my MIL makes this as side dish for chapati. I love it with idli dosa too. I have tasted this type of side dish in Saravana bhavan too at time. (Updated picture,I have used red chilli powder instead of green chillies)
Transfer to serving bowl and enjoy with idly,dosa or rotis!
