Dahi vada is a type of chaat (snack) originating from the Indian subcontinent. It is prepared by soaking vadas in thick dahi (yogurt).

Vigna mungo, also known as black gram, urad bean, urid bean, matimah, matikolai, mash kalai, maas/kalo daal, uzhunnu parippu, ulundu parippu, minapa pappu, uddu, or black matpe, is a bean grown in South Asia. Like its relative, the mung bean, it has been reclassified from the Phaseolus to the Vigna genus. The product sold as black lentil is usually the whole urad bean, whereas the split bean is called white lentil. It should not be confused with the much smaller true black lentil.
