Place lentils in a saucepan and cover with the water, good pinch of salt and the bay leaf. Bring to a boil and then reduce to a simmer. Cook the lentils until just tender, about 20 minutes. Drain the lentils in a sieve.
Meanwhile prepare the vinaigrette. In a small bowl or jar, combine all ingredients for the vinaigrette and whisk until emulsified.
In a large bowl, combine the cooked lentils, apple, fennel, carrot and parsley. Add vinaigrette and toss.
Top with the chopped walnuts and crumbled goat cheese and serve.
Notes
There are two keys to this recipe. The first is dressing the lentils while they are still warm so they soak-up as much flavour as possible. To achieve this, I prepare all the ingredients while the lentils are simmering so the salad is ready to come together once they’re cooked.
The second key is thinly slicing the vegetables. I strongly recommend using a mandolin for the fennel. As for the carrot, a simple vegetable peeler does the trick.
