Place eggs in a large saucepan; add just enough water to the pan so eggs are completely submerged. Bring to a boil over medium heat. Once boiling, cover pan and remove from heat. Let eggs sit 12 minutes in pan, then drain and run under cool water.

Peel eggs, then chop. Transfer chopped eggs to a large bowl.

Stir in mayonnaise and mustard; taste, and add more mayo or mustard depending on your preference, if necessary. Add a dash of garlic powder, salt and paprika and stir to combine; taste and adjust seasonings to your preference. Cover and chill in the fridge until ready to serve.

Serve on bread, toasted or untoasted, with chopped chives and ground pepper on top, if desired.
