Soak daal for several hours. Blend with a little bit of water until it has a batter like consistency (not too runny). Slice up onions and mix with blended daal. Add all spices. Add green peppers depending on how spicy you like them (I use a lot of pepper). Mix. Heat oil in a frying pan about a centimeter deep. Drop spoonfuls of piyaju mixture and fry on both sides until brown. Serve plain or with chutney.
