This is a classic dal, perhaps the most commonly eaten dish in India. Dal is a creamy melange of lentils, garlic and, of course, spices. Serve it as a side dish with curry or roasted meats, or as a main dish with warm naan for scooping.
In a medium saucepan, combine water, lentils, carrots, onion, celery, curry powder, fresh ginger, ground ginger, garlic and salt. Bring to boiling; reduce heat. Simmer, covered, for 20 to 25 minutes or until lentils are tender and liquid is absorbed.
In a small bowl, stir together yogurt, tomato and parsley (or cilantro). Serve with the lentil mixture.
