Preparation: Wash the selected vegetable, dice evenly into small (about a cm square) slices. The more uniform the slices, the better they will cook. Slice the drumsticks, if using into equal length – about 4-5 cms long. The Peel needs to be removed from pumpkin, if using, while the other vegetables such as gourds or drumsticks do not need to be peeled. Wash the moong dal, check for any stones or grit and remove them.
