Fresh India. This is a fabulous book and I have it almost constantly open on my cookbook stand. The recipe I turn to most frequently is one that uses that under appreciated vegetable--beetroot. This recipe is so good, even people who don't like beets (like my brother-in-law) love them.
Although I live alone, I make a whole batch of these and keep some of the patties in the fridge or freezer and fry them up when desired. They can be served as an appetizer or snack, or you can make them the focal point of an Indian meal, with some rice, dal, and raita on the side.
For me, this is almost fast food because I can buy cooked beets in the local supermarkets and greengrocers, and paneer cheese in a little Indian/Suriname store near me. But cooking beets is not hard, and you can make your own paneer too (see Saag Paneer). But I have also made it with drained cottage cheese. I think you could make it with soft feta cheese too (although I would reduce the salt then).
These kebabs are quite soft and delicate. They need to be gently handled, but are easy to make.
