A delightful twist on the classic tuna melt, featuring a flavorful mix of ingredients and a crispy finish.
Preheat your oven to 350°F (175°C).
Ensure the oven is fully preheated for even cooking.
In a mixing bowl, combine the tuna, celery, onion, mayonnaise, and black pepper until well mixed.
Mix gently to keep the tuna chunks intact for better texture.
Spread the tuna mixture evenly on the bottom halves of the buns.
Use a spoon to spread the mixture evenly for consistent flavor.
Top each with a slice of cheese and a slice of tomato.
Press the toppings gently to keep them in place.
Place the assembled buns on a baking sheet and bake in the oven for 12-15 minutes until the cheese is melted and bubbly.
Keep an eye on the cheese to prevent over-browning.
Remove from the oven, top each with a lettuce leaf, and place the bun tops back on.
Serve immediately for the best taste and texture.
