Mix mayonnaise and cucumber water. Season to taste with salt and pepper. Drain the corn. Cut cucumber into slices, ham into cubes. Fold everything into the salad dressing
Wash the lettuce leaves, pluck into bite-sized pieces and arrange on 4 plates. Arrange the ham and corn salad on top
If you don't want to buy extra mayonnaise: just replace it with yoghurt and a little oil. Instead of boiled ham, you can also use pork or pork sausage in your salad
