One look at the ingredient list and you can tell how this potato salad earned it's name. It calls for seven ingredients; one cup each. Since ham numbers among the ingredients, you can serve as a main-dish salad.
1. In a large bowl, mix together the potatoes, ham, egg, apple, cucumber, onion, salad dressing, salt and pepper.
2. Refrigerate, covered, for at least 2 hours. Garnish with parsley, if desired.
