Kae Misr Wot is a red lentil stew. In pan, cook the lentils in 3.5c of the water over low heat for about half hour, or until the lentil are soft and the water has almost completely evaporated. Set aside. In a dry pan, stir fry the onions for 2 mins, add the oil and stir fry 2 mins more. Add the remaining 0.5c water, the tomato paste, chow, and salt and continue to stir. Add the red lentils and mix well over moderate heat for 3 mins until everything is reduced to a thick, well seasoned puree. Serve warm with Injeera.
