Ingredients

• 2 5-ounce cans Canned tuna
• 0.5 cups Mayonnaise
• 0.25 cups Celery, finely chopped
• 0.25 cups Red onion, finely chopped
• 2 teaspoons Dijon mustard
• 1 tablespoon Lemon juice
• 0.5 teaspoons Salt
• 0.25 teaspoons Black pepper
• 1 cup Swiss cheese, shredded
• 6 Soft sandwich buns
• 2 tablespoons Butter, softened
• 2 tablespoons Parsley, chopped (optional, for garnish)

Directions

Step 1

Preheat your oven to 375°F (190°C).

Step 2

In a medium-sized mixing bowl, combine the drained tuna, mayonnaise, celery, red onion, Dijon mustard, lemon juice, salt, and black pepper. Mix well to create a creamy tuna filling.

Step 3

Slice each sandwich bun in half horizontally, but do not cut all the way through, so the halves remain attached. Gently spread the buns open, being careful not to tear them.

Step 4

Spread a thin layer of softened butter on the inside of each bun half.

Step 5

Fill each bun generously with 2-3 tablespoons of the tuna mixture, ensuring an even distribution of filling.

Step 6

Place the filled buns on a baking sheet lined with parchment paper or foil.

Step 7

Sprinkle shredded Swiss cheese over the top of the tuna filling in each bun.

Step 8

Bake in the preheated oven for 8-10 minutes, or until the cheese is melted and slightly bubbly.

Step 9

Remove the buns from the oven and allow them to cool for a couple of minutes.

Step 10

Optionally, garnish with freshly chopped parsley for a bright and fresh touch before serving.
