Add the lentils to a large pot and cover them with about an inch and a half of water. Bring water to a boil then reduce to a simmer and cook very carefully for 15 to 20 minutes or until just done.  Try to avoid over-cooking the lentils as they are much more appealing when they are still al dente and are not releasing their starch.  Drain lentils in a large colander, rinse with cold water, and set aside. Heat a large,non-stick sauté pan over medium heat and begin slowly browning your sausages,turning them occasionally so they brown evenly. (Sausages can also be grilled for this recipe.)  Meanwhile, heat another large non-stick sauté pan over medium-high heat.  Add the olive oil and then the onion to the pan and sauté until lightly golden.  Add the carrots and celery and sauté until they have browned a little and are softened. Add the garlic, cook a minute or two longer, and then add the cream.  Cook vegetables and cream a couple minutes or until cream has thickened a bit.  Add the lentils to the vegetable mixture,stirring gently to heat the lentils and coat them with the sauce.  Season the lentil mixture with salt and pepper to taste.  Add the fresh herbs to the lentils. When sausages are fully heated and nicely browned, quickly slice each one on the diagonal into 3 large slices. To serve, place large spoonfuls of hot lentils onto heated dinner plates.  Place three pieces of sausage on top of each mound of lentils and garnish with herbs. Serve immediately.  Makes: 6 to 8 servings.
