In a pan, heat oil and add mustard, urad dal and curry leaves. to this, add the chopped onions and green chillies. When they turn to a golden brown, add the chopped spinach and fry well for a couple of mins.
Put a pan and the green dal to cook in it, once that is done, add to the fried spinach and onion along with the tamarind(that has been soaked in water n strained), chopped tomato and salt. Boil for about five minutes..
If you want, you can grind the spinach.. but i like spinach as it is.. and it sure tastes yummy with Roti and Steamed rice.. enjoy~~~
