Zesty Napa Slaw
3 tablespoons cider vinegar
2 tablespoons whole-grain mustard
1 teaspoon kosher salt
Freshly ground black pepper
1/3 cup extra-virgin olive oil
1/2 head Napa cabbage, thinly sliced, about 6 cups
6 scallions (white and green parts), thinly sliced
1 orange or yellow bell pepper, stemmed, seeded, and thinly sliced
1 red apple
2 cups watercress leaves
Instructions:
Whisk the vinegar with the mustard, salt and pepper, to taste, in a large bowl. Gradually whisk in the olive oil, starting with a few drops and then adding the rest in a steady stream to make a smooth, slightly thick dressing. Add the cabbage, scallions, and bell pepper and toss until the vegetables are coated. Serve now or cover and refrigerate for up to 4 hours.
Before serving, grate the apple (with the skin but not the seeds) directly into the slaw, add the watercress leaves, and toss again. Season, to taste, with salt and pepper.
