Kitchari is a well known dish in the Ayurvedic tradition that is nourishing as well as easy to digest. It can be eaten for breakfast, lunch or dinner. Sometimes it is a cleanse unto itself, where only kitchari is eaten for a set period of time.
There are a lot of spices in this dish, and I would recommend getting them all. Cooking with Indian spices is a great way to eat legumes and vegetables.
