Begin the full recipe by hard boiling the 4 large eggs and using a box grater to grate each egg into a medium size mixing bowl. Set aside.
Open a 12 ounce can of tuna and drain off the water. Add to the bowl with the grated eggs. Add the 3 tablespoons mayonnaise, ¼ cup sweet relish, 1 tablespoon fresh parsley, ½ teaspoon salt, and ¼ teaspoon ground black pepper.
Stir all of the ingredients together until combined. Use it to make a sandwich or serve it on a bed of lettuce and enjoy it with your favorite crackers. Enjoy!
