Idli Sambar

I went to a very small Indian restaurant, and this is one of the items they said was vegan. Idli is a steamed rice cake. Sambar is a spicy soup. This was excellent. It's difficult to describe the flavor of sambar because nothing I've eaten tastes anything like it. This was one of the spiciest foods I've ever eaten, but it didn't really burn my mouth like peppers. It did light up my whole mouth with amazing flavor. The idli was almost tasteless but added an interesting texture. I looked up some recipes for sambar and idli just to see if they are typically vegan. Most recipes I found are vegan. And it looks like the sambar could be very cheap and easy to make at home.
