Ingredients

3 navel oranges

2 tablespoons olive oil

1 tablespoon white-wine vinegar

2 teaspoons Dijon mustard

Coarse salt and ground pepper

4 bunches watercress (about 1 1/2 pounds total), thick ends removed

Preparation

Slice off both ends of oranges. With a sharp knife, cut away peel and pith. Cut along membranes to remove segments. Squeeze 2 tablespoons juice from membranes into a small bowl.

Add oil, vinegar, and mustard; whisk to combine, and season with salt and pepper.

In a large bowl, toss together watercress and dressing; top with orange segments, and serve immediately.
