Add the eggs to a pan of water and cover by one inch of water. Bring to a boil. Reduce to a simmer. Simmer for 7 minutes, then drain and rinse the eggs immediately under cold water. Set aside until cool enough to handle.
Step 2
Once the eggs have cooled, gently crack the shells so that you can carefully peel the shell away. Slice each egg in half lengthwise. Use a teaspoon to carefully scoop the yolk from the whites and set aside. Take care not to break the egg whites.
Step 3
Add the tuna, mayonnaise, lemon zest, paprika, salt, pepper and cooked egg yolks to a small bowl. Mash together until well combined. Taste and adjust seasonings as desired.
Step 4
Divide the tuna and egg mixture evenly between the hollowed egg whites. Finely chop the fresh parsley. Sprinkle the filled eggs with fresh parsley to serve.
