I made these exactly as written and did not care about the end result. I thought they were too rich and the taste was off.
1 (4.5 ounces) can tuna, drained and flaked
2 teaspoons sweet pickle relish, drained
1 teaspoon mustard
¼ teaspoon white sugar (Optional)
⅛ teaspoon onion powder
2 ½ tablespoons mayonnaise, or as needed
salt and pepper to taste
1 pinch paprika, or as desired
Place eggs in a saucepan; cover with water. Bring to a boil, remove from heat, and let eggs stand in hot water for 15 minutes. Remove eggs from hot water, cool under cold running water, and peel.
Cut eggs in half lengthwise; place yolks in a small bowl. Mash egg yolks with a fork; stir in tuna, pickle relish, mustard, sugar, and onion powder. Stir mayonnaise into tuna mixture until mixture is creamy but remains firm; season with salt and pepper.
Place egg whites cut-side-up on a serving platter. Spoon tuna mixture into egg white halves; sprinkle with paprika.
