Eggs and Ham Sandwich

.

hard boiled eggs, peeled and diced using an egg slicer
ham, very finely diced
some red onion, very finely diced
salt and pepper

mayonnaise, thinned with buttermilk to the consistency of cream
mustard of your choice, I like Dijon

To dice up the eggs I place an egg in the egg slicer and slice it. Then, carefully lifting up the egg and opening the slicer, I carefully turn the sliced egg 90 degrees and then reslice the egg. When you've got you eggs diced up add the ham and onions and stir with a fork. Thin the mayonnaise with the buttermilk and then stir in the mustard. Add to the egg mixture and stir up gently. Taste and adjust the salt and pepper as needed.
