Nan’s Mashed Potato Salad

"Nan’s Mashed Potato Salad has all the flavor of the best potato salad you will ever want. Creamy, dreamy, and the perfect side dish for Easter, Mother’s Day, and all your gatherings all summer long. Pretty simple ingredients, but all have a purpose for flavor and more. Why put vinegar on potatoes for potato salad? Apple cider vinegar plays a two-part role in your potato salad; it gives the potatoes a little tang and also keeps them from drying out."
