Savory Potato Salad

3 pounds red potatoes, scrubbed
1 1-oz. packet vegetable soup mix
1/4 cup red wine vinegar
Pepper
2 stalks celery, minced
2 tablespoons minced red onion
2 teaspoons Dijon mustard
1 cup mayonnaise
Zest of 1 lemon
1/2 cup packed arugula leaves, coarsely chopped
1/4 cup packed parsley leaves, coarsely chopped



Cover potatoes with 1 inch of cold water in a large pot or Dutch oven. Bring to a boil, then reduce heat to medium. Cook until potatoes are tender and a knife inserted in center of a potato meets no resistance, 25 to 30 minutes.

Drain and let cool slightly. When potatoes are cool enough to handle, chop into 1-inch pieces and place in a large bowl. Toss potatoes with soup mix, vinegar and pepper to taste. Cover bowl with plastic wrap and refrigerate until cool, 20 to 25 minutes.

Toss potatoes with celery, onion, mustard, mayonnaise and lemon zest. Fold in arugula and parsley. Taste and adjust seasoning, if necessary. Serve immediately, or chill, covered, until ready to use.
