6 cups red potatoes (about 6 medium potatoes)
1½ cups celery (about 2 stalks)
½ cup light mayonnaise
½ cup low-fat, plain yogurt
1 tablespoon mustard
1 tablespoon vinegar
1 tablespoon pickle relish
½ teaspoon black pepper
½ teaspoon cayenne pepper (optional)
1 hard-boiled egg, chopped (optional)
Wash your hands well with soap and hot water.
Wash celery stalks and lay on a cutting board. Cut off both ends and cut into 4-6 strips lengthwise, depending on width. Cut across ends until all pieces are chopped. Add to bowl.
Wash and cube potatoes and place in a sauce pan. Cover potatoes with water and boil on medium high for 10-15 minutes. Drain.
In a large mixing bowl, stir together mayonnaise, yogurt, mustard, vinegar, pickle relish, black pepper, and cayenne pepper. Add cooked potatoes, celery, and hard-boiled egg. Stir to coat evenly.
Refrigerate until ready to serve.
Refrigerate leftovers within 2 hours.
