Ingredients

1 cup black or Le Puy lentils, picked over and rinsed

1/2 yellow onion

2 cloves garlic

2 teaspoons grated peeled fresh ginger (from a 3/4-inch piece)

1 teaspoon Dijon mustard

3 tablespoons white-wine vinegar

Coarse salt and freshly ground pepper

1/2 cup extra-virgin olive oil

4 carrots, peeled and shaved into thin strips with a peeler

1 cup packed fresh flat-leaf parsley leaves

Preparation

Bring lentils, onion, garlic, and 4 cups water to a boil in a saucepan. Reduce heat; simmer until tender, about 20 minutes.

Meanwhile, whisk together ginger, mustard, and vinegar in a small bowl. Season with salt and pepper. Gradually whisk in oil. Toss together carrots, parsley, and half of dressing in a bowl. Season with salt and pepper.

Drain lentils; discard onion and garlic. Toss lentils with remaining dressing in another bowl. Transfer to a platter, top with carrot mixture, and serve.
