A simple recipe, with few ingredients and cooked in minutes -- Pithla is a side, you can make when you are out of vegetables (or anytime). Usually, it is served with "bhakris" -- which are flat-breads made of jowar(sorghum) or bajra(pearl millet) flours. You can make it liquidy like a soup or a dal, or slightly thickened !! Whatever way you make it, it tastes great.
