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.
To hard-boil eggs: Place eggs in a single layer in a saucepan; cover with water. Bring to a simmer over medium-high heat. Reduce heat to low and cook at the barest simmer for 10 minutes. Remove from heat, pour out hot water and cover the eggs with ice-cold water. Let stand until cool enough to handle before peeling.
