This is the South Indian version of Palak Paneer or Saag Paneer, but without the paneer. Serve this dish over rice and crumple potato chips on top. Serve yogurt on the side. You can substitute any kind of greens, or a mix of greens, for the spinach. And fresh is better. Adjust spices to your taste and your tolerance. Make sure you use unsweetened coconut. You can use other lentils, but toor dal or mung dal is best. Adjust salt according to how salty you cooked the dal.
