This is a South Indian tomato soup called Rasam. It is very quick to make and can be eaten by itself or as part of a larger meal. This is a vegan version, but you can use chicken stock if you prefer.
Rasam was one of my first introductions to South Indian cooking. Now I've used it to introduce my mother to the cuisine. The only drawbacks to this recipe derive from personal tastes. I don't like oil or ghee in the poppu/tadka for rasam. Let's hope more people try this. It's the best cold remedy and light meal I can imagine. - 22 Jan 2010 (Review from Allrecipes USA and Canada)
