6 hard-boiled eggs
around 1-2 cups mayo (depending on how much mayo you like, and whether you'll be adding extras to it; I prefer Kraft Mayo or Miracle Whip for a perfectly creamy, tangy taste)
salt and pepper to taste
finely-chopped ham (optional)
grated cheese (optional)
With a fork, mash hardboiled eggs. Add the mayo and other ingredients, season according to your preference.
Depending on how much you spread, this recipe can almost provide for an entire loaf of bread.
Some also add some grated/chopped onion to it for some zing.
