2 1/2 pounds small red potatoes
3/4 cup chopped green onions
3/4 cup chopped celery
3/4 cup fat-free sour cream
1/4 cup reduced-fat mayonnaise
2 tablespoons minced fresh parsley
1 tablespoon white wine vinegar
1 1/2 teaspoons salt
1/4 teaspoon pepper
1/4 teaspoon celery seed
1/2 cup crumbled blue cheese
Place potatoes in a large saucepan and cover with water. Bring to a boil. Reduce heat; cover and cook for 15-20 minutes or until tender. Drain. Let stand until cool enough to handle or refrigerate overnight. Peel and cube potatoes.
In a large bowl, toss the potatoes, onions and celery. In a small bowl, combine the sour cream, mayonnaise, parsley, vinegar, salt, pepper and celery seed. Pour over potato mixture; toss to coat. Sprinkle with blue cheese. Cover and refrigerate for several hours before serving.
