Heat a pan and add the oil. When the oil becomes hot, add the cumin seeds, tamarind, green chillies, onions and saute until the onions start turning golden brown. Set them aside to cool.

 Now add the peanuts and roast them until they turn golden. Set them aside along with the onions.

Now add the spinach and saute for a minute or so until they wilt.

Grind everything together with salt and water as needed to a chutney.

Serve your spinach chutney with idli / dosa or even with rice.
