Ingredient Notes
- American cheese: Melts smoothly and blends perfectly into the warm tuna mixture.
- Hard-boiled eggs: Add richness and extra protein.
- Tuna: Use water-packed tuna, well drained and flaked.
- Green pepper: Adds mild crunch and freshness.
- Onion: Finely chopped so it softens as the buns bake.
- Pimiento-stuffed olives: Bring a salty, savory pop of flavor.
- Sweet pickle relish: Adds sweetness and tang—classic tuna salad flavor.
- Mayonnaise: Binds everything together; add just enough to moisten.
- Hamburger buns: Soft or slightly toasted; buttered before filling for extra flavor.
Steps to Make Hot Baked Tuna Buns
- Combine the cheese, chopped eggs, tuna, green pepper, onion, olives, and relish in a bowl.
- Add mayonnaise until the mixture is well moistened.
- Split and butter the hamburger buns.
- Divide the tuna mixture among the buns and wrap each in foil.
- Bake until hot and the cheese is melted.
Tips
- Drain the tuna thoroughly to prevent a watery filling.
- Chop ingredients finely so the mixture spreads evenly on the buns.
- Use softened butter—cold butter can tear the buns when spreading.
- Wrap tightly in foil to keep the buns soft and prevent drying.
- For a toasted bun, open the foil halfway through baking.
- These can be assembled ahead and refrigerated until baking time.

Serving Suggestions

- Add sliced tomatoes or shredded lettuce after baking for freshness.
- Garnish with a sprinkle of paprika or chopped parsley.
