This dish is an Indian stir fry using whole Mung Dal or Mung Beans – those green round unhulled lentils that are less common than their sisters, the yellow, skinned, split mung dal.
First the mung is sprouted by soaking them and then keeping them moist for a few days. When the mung have sprouted, they are stirfried with spices.
You could try this with purchased mung bean sprouts. It would be a slightly different dish because the sprouts are left to grow longer and the beans themselves will be softer.
