If you don't take hard-boiling the eggs into account, this is a super fast and healthy snack, taking only a minute or two to prepare. Its also good for a variety of special needs diets. For added texture and a pop of nutrients I sprinkled poppy seeds on the egg before adding the mayo.

A hard-boiled egg is a protein-packed snack on its own—give it a little more pizzazz with a bit of mayo and mustard on top.
