A delightful twist on the classic tuna melt, combining creamy and savory flavors with a crispy, golden crust.
Combine the tuna, Swiss cheese, sour cream, mayonnaise, onion, celery, and pepper in a mixing bowl until well blended.
Ensure the tuna is well-drained to avoid a soggy filling.
Spread the prepared filling evenly over half of the bread slices.
Use a knife or spatula to spread the filling smoothly.
Top with the remaining bread slices and butter the outsides of each sandwich.
Butter the bread evenly for a golden crust.
Heat a griddle or skillet over medium heat and cook the sandwiches for 4-5 minutes on each side until golden brown and the cheese is melted.
Press the sandwiches lightly with a spatula for even cooking.
Serve the sandwiches warm, optionally paired with a side salad or soup.
Cut the sandwiches diagonally for a classic presentation.
