German Potato Salad

Red potatoes
Olive oil
White vinegar
Onion (Walla Walla Sweets work well)
Salt
Pepper
Water

There are no measurements here, since this is an old German recipe that my Grandpa Berger used to make. He made a batch big enough for an army, but then again, we had seven kids.

Start with about 3-5 pounds of potatoes. Slice them very thin after they have been cooked, cooled, and peeled. Thinly slice 1/2 large onion and chop into fairly small pieces. Add about 6-8 heaping tablespoons of oil and 3-4 tablespoons of vinegar. Add about a fourth cup warm water. Salt and pepper to taste. Keep refrigerated.
