Golden Tuna Melt Sandwich (Printable)

Crispy grilled sandwich with creamy tuna salad and melted cheese, ready in 18 minutes

# What You'll Need:

→ Tuna Salad

01 - 1 (5 oz) can tuna in water, drained
02 - 2 tablespoons mayonnaise
03 - 1 teaspoon Dijon mustard
04 - 1 small celery stalk, finely diced
05 - 1 tablespoon red onion, finely diced
06 - Salt and black pepper to taste

→ Sandwich Assembly

07 - 4 slices sandwich bread (white, whole wheat, or sourdough)
08 - 1 tablespoon butter, softened
09 - 4 slices Swiss or cheddar cheese
10 - 2 slices tomato (optional)

# Step-by-step:

01 - Combine drained tuna, mayonnaise, Dijon mustard, celery, and red onion in a mixing bowl. Mix thoroughly until evenly distributed. Season with salt and pepper to taste.
02 - Spread softened butter evenly on one side of each bread slice. Ensure complete coverage for even browning.
03 - Place half the tuna salad on the unbuttered side of two bread slices, spreading to edges. Add tomato slices if using, then top each with 2 cheese slices. Cover with remaining bread, buttered side facing outward.
04 - Heat skillet over medium heat. Place sandwiches in pan and cook for 3–4 minutes per side, pressing gently with spatula. Flip once when bread turns golden brown. Continue until cheese is fully melted and both sides are evenly toasted.
05 - Remove from heat and slice each sandwich diagonally in half. Serve immediately while hot and cheese remains melted.
