Hard-boiled eggs.
Cut the smoked ham into cubes.

Cut the eggs into cubes.
Very small (slightly larger than on a grater) cut a sour or sweet-sour Apple. I prefer Granny or Golden delicious. To make the salad even more tender, peel the apples.
Pour all the ingredients into a bowl, add the corn and mayonnaise. Mix and enjoy.
