Season, to taste, with salt and freshly ground black pepper. Brush the duck legs with the honey and pan- roast them, skin- side down, in a non- stick pan over a medium heat for five minutes or until crisp and golden- brown. The honey will caramelise very quickly, so be careful not to let it burn.
To serve, spoon the lentils onto serving plates and top with the duck legs. Alternatively, arrange the duck legs on top of the lentils in a large pot and serve at the table.
