Cover the pot, and heat on the stove over medium high until it begins to boil. Once boiling, remove the lid, reduce the temperature to medium/medium-low and gently boil for 10-15 min, or until the lentils absorb most of the liquid. Turn off the heat, cover and let the lentils sit for 5 min to continue absorbing the liquid without becoming mushy.
Taste and season to preference with additional salt and pepper. Serve immediately. Garnish with fresh cilantro or dill.
