Ingredients

• 2 5-ounce cans canned tuna
• 1/3 cup mayonnaise
• 1 tablespoon dijon mustard
• 1 stalk, finely chopped celery
• 2 stalks, finely chopped green onion
• 1 teaspoon lemon juice
• 1/4 teaspoon salt
• 1/4 teaspoon black pepper
• 4 slices (whole grain or white) sliced bread
• 4 slices cheddar cheese
• 2 tablespoons (optional, for toasting) butter

Directions

Step 1

Preheat your oven to 400°F (200°C) or set your broiler to high.

Step 2

Drain the canned tuna well and transfer it to a medium-sized mixing bowl.

Step 3

Add mayonnaise, Dijon mustard, chopped celery, green onion, lemon juice, salt, and black pepper to the bowl with the tuna. Mix well until evenly combined.

Step 4

Lightly butter one side of each slice of bread (optional for added richness). If not buttering, proceed to the next step.

Step 5

Place the slices of bread on a baking sheet, buttered side down if applicable.

Step 6

Divide the tuna mixture evenly among the four slices of bread, spreading it out to cover the surface but leaving a small edge around the perimeter.

Step 7

Top each sandwich with a slice of cheddar cheese.

Step 8

Bake the sandwiches in the preheated oven for 8–10 minutes, or until the cheese is fully melted and slightly bubbly. If using a broiler, cook for 2–3 minutes, watching carefully to avoid burning.

Step 9

Remove the sandwiches from the oven and let them cool for 1–2 minutes before serving.

Step 10

Serve warm and enjoy your hot tuna sandwiches with a side salad, chips, or soup!
