2 1/2 lb baby red potatoes, cut into 1-inch cubes
2 tbsp apple cider vinegar
1 tbsp olive oil
1/2 cup whole buttermilk
1/4 cup reduced-fat sour cream
1/4 cup reduced-fat mayonnaise (I use olive oil mayo)
1 tbsp Dijon mustard
2 carrots, grated
1/2 cup chopped celery
1/2 cup sliced radishes
1/2 cup steamed, cut fresh green beans
1/4 cup finely chopped fresh parsley
1 tbsp lemon zest
1 garlic clove, minced
Sea salt and freshly ground pepper to taste
In a large saucepan, bring the potatoes to boil in salted water(enough to cover); reduce heat and simmer 7 to 10 minutes until tender. Drain potatoes, place in a large bowl and sprinkle with the vinegar and olive oil; toss gently. Allow to cool completely.
Whisk the buttermilk, sour cream, mayonnaise, and Dijon mustard together. Stir in the carrots, celery, radishes, green beans, parsley, lemon zest, and garlic. Season the mixture with the salt and pepper to taste.
Spoon the buttermilk mixture over the the cooled potato mixture and toss gently to coat.
Cover the salad and refrigerate at least 1 hour but up to 24 hours. (A great make-ahead dish!)
Note: Do not peel the potatoes. Red potatoes contain nutrients that promote heart health and lower one's cancer risk when left in the skins.
