Allow the chana dal to soak for at least 2 hours in lukewarm water. It is ready when the dal is soft all around. Drain the water.
Mix the chana dal with the rest of the chopped vegetables.
Mix all the salad dressing ingredients thoroughly.
Toss the salad dressing with the vegetables. Allow the mixture to sit for a half an hour to an hour so that the salad becomes marinated and the flavors combine.
