Parippu is south Indian dal. This is a modification of the parippu recipe in The Food of India published by Murdoch Books. You can switch out the greens for another vegetable like chayote squash or green beans. You can also add carrots. To increase spiciness, just increse the amount of spice, but keep the cumin, tumeric, corriander ratio the same. Serve it over rice, and if you like, crumble potato chips on top.
