My mom's classic potato salad is a family favorite, and it's sure to make the perfect side dish at any backyard barbecue!
Boil the potatoes until fork-tender.
Drain the potatoes, allow them to cool, then peel them and cut them into bite-sized pieces.
Cook the eggs, allow to cool, then peel (if necessary) and chop into small pieces.
Add the potatoes, eggs, onions, salt, and pepper to a large bowl, then chill in the fridge until ready to serve.
Before serving, mix together the mayonnaise, sour cream, and mustard, then fold gently into the other ingredients.
Serve and enjoy!
