Bring lentils to a boil in enough water to cover. At the same time, make a spice paste by crushing together the garlic, cinnamon, cumin, peppers & salt plus 2 ts water. After 2 or 3 minutes, drain the lentils thoroughly. Add the spice paste, followed by the onions, oil & bay leaves. Stir over moderate heat for several minutes then add water to cover. Reduce heat, cover pot & simmer until lentils are tender. Uncover for a while before serving so that the mixture can thicken.
