I fell in love with German Potato Salad when I was in high school and dated a guy who's mom was German. My mom and I now use this recipe. This is really more of a side dish than a salad. The vinegar gives it a nice tangy flavor. We add white, yellow or red onion rather than green. Just don't have green on hand usually. The onions and bacon give the salad a crispy texture. I much prefer this to American potato salad with the mayo.
