Put the lentils and water in a medium saucepan and bring to a boil. Reduce heat and simmer, covered, until the lentils are soft, about 20-30 minutes. Check often and add water if it seems dry.
Drain all water from the lentils. Put them and all remaining ingredients into the food processor and blend until smooth. Check seasonings and add more lemon juice, berberé, and salt. Transfer to a covered bowl, sprinkle with chopped chili peppers, if desired, and serve chilled or at room temperature.
