Dhonepatar chaatney

So much of my childhood tastes of this :).

Ingredients:
1 Big bunch of fresh coriander
1 Onion
3-4 Green chillies(depending on how spicy you want it)
1 Lemon juice
4-5 Garlic cloves
7-8 Pudina leaves
1/4 cup of tamarind
2 tsp mustard oil
salt to taste
Method:
Soak tamarind in water till it is tender, take out the seeds and make a paste. Add all the ingredients (excpet oil and salt) into a blender and blend to make a smooth paste. and finally add the mustard oil (this will preserve the green colour).
