Kaddu ka dalcha-hyderabadi style Recipe

This is a traditional hyderabadi vegetarian cuisine where bottlegourd (lauki) is cooked with chana dal (bengal gram), called "kaddu ka dalcha". Kaddu means bottlegourd in the local lingo. Though there are many versions to it, it is generally cooked in the same way as mutton dalcha minus mutton, eggplants and potatoes. It is also cooked sometimes with tuvar dal (pigeon pea lentil). It can be prepared in a soup form to be enjoyed with rice. Here in this recipe i kept it slightly semi-dry to be had with chapatti. Serve this delicious dish garnished with onion rings and coriander leaves.
