:::For the Lentil Soup:2 tablespoons butter:::

1 carrot, peeled and diced
1 celery stalk, diced
2 cups (1 pound) dried brown lentils, rinsed

Directions
Make the herbed yogurt: In a small bowl, stir together the yogurt, tarragon, parsley and lemon zest. Season with salt and pepper, and set aside.
Make the soup: In a large pot, heat the butter over medium-high heat. Add the garlic, onion, carrot and celery, and cook until soft and slightly caramelized, 5 to 7 minutes. Add the lentils, stock and bay leaf, and bring to a boil. Reduce the heat to a simmer and cook until the lentils are tender, about 45 minutes.
Discard the bay leaf and transfer a third of the soup to a blender. Purée until smooth, then return to the pot. Stir in the lemon juice, tarragon, parsley and lemon zest. Season with salt and pepper. Divide the soup between bowls and spoon yogurt onto each. Garnish with chopped tarragon and parsley, and serve immediately.
