1 tablespoon Dijon mustard
1 tablespoon red wine vinegar
1/2 tablespoon lemon juice
3 tablespoons extra-virgin olive oil, or as needed
salt and pepper to taste
4 heads Belgian endive
1/3 cup pine nuts
1 tablespoon chopped fresh parsley, for garnish
In a medium bowl, whisk together the Dijon mustard, red wine vinegar and lemon juice. Whisk in olive oil slowly until you have an almost creamy consistency. Taste and season with salt and pepper. Set aside.
Cut endive heads crosswise into rings. Remove the hard end of the stems and discard. Rinse in a colander, shaking to separate the slices into rings. Set aside to drain.
In a large dry skillet over medium heat, toast the pine nuts. Stir constantly so that they do not burn. Once the pine nuts are golden, throw in the endive rings. Once it has warmed just slightly, pour in the dressing and toss to coat. Reduce the heat slightly if the endive is wilting too quickly. You want to maintain some crispness and texture.
If you have guests to impress, throw in the parsley. The sharp green flecks will brighten the dish and enhance the flavour, but the salad is in no way lacking without. Serve immediately. It is best served directly from the pan to the plate. If is put in a bowl, the dressing will settle at the bottom and be difficult to toss again without damaging the endive.
