Cabbage-onion soup

I got this real huge cabbage from the store that seemed to never finish. So I boiled 'em up, added some salt and pepper and got a fantastic soup out of it. Here's how you can try the same.

Microwave cabbabe and onion with water for 7-8 minutes. You can pressure cook it for one whistle if you are not a microwave person. Once done, put the vegetable in a blender. Do not add water here. Also, keep the stock separate. Just blend the vegetable alone. Heat this puree on a wok for 2 min and add the stock. Add salt and pepper as per your liking. Serve this hot, garnished with corriander and lemon.
