Ingredients
Tuna Salad
- 20 ounces tuna packed in water (about 4 cans, drained & flaked)
- 1/4 cup celery (finely diced)
- 2 tablespoons red onion (finely minced)
- 1 teaspoon flat-leaf parsley (finely minced)
- 1/2 cup mayonnaise
- 1 teaspoon Dijon mustard
- 1 tablespoon fresh lemon juice
- Salt and black pepper to taste
Sandwich
- 8 slices bread
- 8 slices cheese (cheddar or your preferred melting cheese)
- 1/4 cup butter (softened, optional)
- 2 small tomatoes (sliced thin, 2 slices per sandwich)
Instructions
- Make Tuna Salad: In a large bowl, combine the drained and flaked tuna with finely diced celery, minced red onion, and flat-leaf parsley. Stir to mix the ingredients evenly.
- Mix Salad Dressing: Add mayonnaise, Dijon mustard, and fresh lemon juice to the tuna mixture. Stir well until fully combined. Season with salt and black pepper to taste.
- Preheat Oven for Broiling: Set your oven to the broil setting to prepare for toasting the bread.
- Toast Bread Under Broiler: Butter the bread slices if desired and place them on a parchment-lined baking sheet. Broil until golden brown, then flip each slice to toast the other side. Remove and allow to cool slightly.
- Assemble Open-Faced Sandwich: Spread the prepared tuna salad generously over one toasted bread slice. Top with one slice of cheese on each.
- Broil to Melt Cheese: Return the sandwiches to the oven and broil until the cheese melts and becomes gooey. Keep a close eye to prevent burning.
- Add Tomato and Final Seasoning: Remove the tuna melts from the oven and place thin tomato slices on top. Add additional salt and pepper if desired.
- Alternative Baking Method – Preheat Oven: Instead of broiling, preheat oven to 400°F (200°C) for baking.
- Bake Bread Slices: Butter one side of each bread slice (optional) and place butter-side up on a parchment-lined baking sheet. Bake until golden brown, about 5 minutes, then flip and toast the other side. Let cool slightly.
- Assemble and Bake Sandwiches: Spread tuna salad over toasted bread slices, top with tomato slices and a slice of cheese. Bake in the oven until cheese melts, approximately 10 minutes.
Notes
- You can use your preferred type of melting cheese such as cheddar, Swiss, or mozzarella.
- Butter on the bread slices is optional but enhances flavor and promotes browning.
- Watch the sandwiches carefully while broiling to avoid burning the cheese or bread.
- Leftover tuna salad can be stored in the refrigerator for up to 2 days.
