Cook tiny French lentils until just tender and toss with a tangy shallot vinaigrette. Add diced fennel, fresh mint, and soft goat cheese and you have a dish that strikes a balance of rustic and elegant. It's enormously satisfying and nourishing. Enjoy as a main course lunch or supper or a side dish to roast chicken or fish.
Rinse the lentils with water in a colander and look over carefully, removing any tiny stones or debris. Put in a medium pot with the garlic and bay leaf and cover by 3 inches with water. Bring to a boil. Once water boils, drop the heat until it simmers. Simmer for 10 minutes, add 2 teaspoons salt, and continue simmering until the lentils are just tender, but not mushy (15 to 20 minutes total simmer time).
While the lentils cook, in a medium bowl, whisk together the mustard, salt, vinegar, oil, several cracks of black pepper, and sumac. Add the shallot and whisk again.
Notes: French lentils, also called lentils de Puy, are smaller and darker in color than standard green lentils. They hold their shape well when cooked and are well suited for salads. If you can't find them, use brown lentils. You may need to adjust the cooking time.
