Sautee the onions in oil in a stock pot. When the onions are done, add the bouillion, water, peppercorns, salt, and lentils. Cover and cook until lentils are soft. Then ladle the soup into a blender or food processor and puree until smooth. This will give the soup its velvety texture. Serve hot.
This recipe is so quick, easy, and satisfying on cold days...
