2 tablespoons mayonnaise

2 slices sourdough bread
2 tablespoons butter
4 slices American cheese
3 slices tomato thinly sliced

US Customary - Metric

Instructions

Drain the tuna thoroughly. Place it in a small bowl with the mayonnaise and black pepper. Mix until well combined, breaking the tuna into smaller pieces as you stir.
Butter one side of each slice of bread.
Place the bread butter-side down in a warm skillet. Top each slice with American cheese.
Spread the tuna mixture evenly over one slice of bread. Arrange the tomato slices over the tuna.
Cook until the bread is golden brown and the cheese has melted.
Carefully place the cheese-topped slice over the tuna and tomato side to form the sandwich.
Remove from the skillet, rest for a few minutes, cut in half and serve.

Notes

Drain the tuna thoroughly before mixing to prevent the filling from becoming watery.
Solid white albacore tuna packed in water is recommended for the best texture and flavor.
American cheese provides the closest match to a traditional diner-style tuna melt, but other melting cheeses may be substituted.
Thinly sliced tomatoes work best and help keep the sandwich easy to assemble.
