Kae Atar Wot is a green pea stew. In pan, cook peas in 3.5 cups of the water over low heat for about half hour, or until the peas are soft and the water has almost completely evaporated. Set aside. In dry pan, stir fry onions 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 split peas and mix well over moderate heat for 3 mins, until everything is reduced to a thick, well seasoned puree. Serve warm with Injeera.
