French Lentil Salad

This lentil salad is delicious, easy to make, and great either warm or cold. I make a lot of bean salads to take to campus for lunch, and this is by far the best one yet, much better than the mass of red lentils and red pepper in my fridge that is waiting for me to give up and just finish it. I could eat this salad every week and not get tired of it (and I might!).

French-Style Warm Lentil Salad
1 cup French green (Puy) lentils, picked over and rinsed (I had regular, so that's what I used)
3 cups water
1 Turkish bay leaf
½ tsp. salt, divided
1 small onion, finely chopped
1 medium carrot, finely chopped
1 celery stalk, finely chopped
2 medium garlic cloves, minced
1 tsp finely chopped fresh thyme
5 Tbsp. olive oil, divided
2 Tbsp. plus ½ tsp. red wine vinegar
½ Tbsp. Dijon mustard
Crunchy sea salt, for serving
2 Tbsp. finely chopped Italian parsley, for serving

In a medium saucepan, bring the lentils, water, and bay leaf to a boil over medium-high heat. Reduce the heat and simmer, covered, until almost tender, about 15 minutes. Stir in ¼ teaspoon salt, and then simmer, covered, for another 3 to 5 minutes, until tender but not falling apart.

While the lentils simmer, warm 1 tablespoon of the oil in a 12-inch skillet over medium-low heat. Add the onion, carrots, celery, garlic, thyme, and 1/8 teaspoon salt, and cook, stirring occasionally, until the vegetables are just softened, about 7 to 9 minutes.

Meanwhile, make the vinaigrette. In a small bowl, whisk together 2 tablespoons vinegar, mustard, and remaining 1/8 teaspoon salt. Add the remaining 4 tablespoons olive oil, and whisk to emulsify.

When the lentils are ready, drain them in a colander or sieve, and discard the bay leaf. Dump them into the skillet with the vegetables, and add the vinaigrette. Cook over low heat, stirring gently, until heated through. Stir in the remaining ½ tsp. vinegar, and serve warm, with crunchy salt and parsley for sprinkling.
