Here's my grandmother's recipe. She usually substituted hot dogs or bologna for the ham to save money.

Ham Salad (makes 3 cups)

1# ham, hot dogs, or bologna
3 hard boiled eggs
3 Tblsp pickle relish
Mayonnaise

Grind ham (or hot dogs or bologna) and eggs. Add pickle relish and enough mayonnaise to make a spread. Be careful not to add too much mayo or the salad will be watery. Refrigerate and use cold on sandwiches or small breads or crackers. You can also use it hot and make open-face sandwiches topped with cheese--heat it oven until cheese melts and serve immediately.
