Gotta have a good lentil soup recipe.
Heat the oil in a soup pot over high heat. Add the onion and sauté until it begins to color around the edges, 5 to 7 minutes. Meanwhile, mince or pound the garlic in a mortar with 1 teaspoon salt. Work the tomato paste into the onion, then add the garlic, celery, carrot, bay leaves, and parsley and cook for 3 minutes. Add the lentils, 2 quarts broth, 1/2 teaspoon salt and bring to a boil. Lower the heat and simmer, partially covered, until the lentils are tender, 25 to 35 minutes. Stir in the mustard and vinegar. Taste and add more of either as needed. Check the seasoning and adjust with plenty of black pepper. Remove the bay leaves, and serve garnished with the chopped celery leaves and parsley. The longer the soup sits before serving, the better it will taste.
