Instructions
- Make the Tuna Salad:
- In a mixing bowl combine the drained tuna with mayonnaise or Greek yogurt. Add Dijon mustard followed by garlic powder, onion powder, salt, and black pepper. Stir together until evenly mixed. Fold in the finely diced jalapeño, shredded cheddar cheese, and green onions if using. Make sure everything is well incorporated but not mashed.
- Assemble the Sandwiches:
- Butter one side of each bread slice lightly. Heat a skillet or griddle over medium heat and place two slices of bread buttered side down on the surface. Sprinkle a generous amount of shredded cheddar cheese on each slice now on the skillet. Next, spread the tuna mixture on top of the cheese evenly. Place the other two bread slices on top, butter side facing up.
- Grill the Tuna Melts:
- Cook the sandwiches for about three to four minutes per side. Press gently with a spatula to compact the sandwich slightly and encourage even toasting. Watch for the bread to turn a rich golden brown and the cheese to melt thoroughly. Flip carefully to cook the second side. Remove them from heat and let rest for one minute before cutting.
- Serve and Enjoy:
- Slice the melts in half diagonally or down the middle. Serve while hot with pickles, potato chips, or a crisp side salad for a balanced meal.

Cheddar cheese is my go-to ingredient here because of how beautifully it melts and pairs with the smoky heat from the jalapeño. Years ago, making these melts on a chilly evening brought my family together around the table with smiles all around. It was one of those meals where everyone felt cozy and content.
Storage Tips
Store leftover tuna salad in an airtight container in the refrigerator for up to three days. It keeps well but avoid freezing as it alters texture. Prepare sandwiches fresh or reheat grilled sandwiches in a skillet on low heat or in an air fryer for a few minutes to crisp up again.
Ingredient Substitutions
Try canned salmon instead of tuna for a slightly richer and different flavor. Use pepper jack cheese for an extra spicy melt or Swiss for a milder taste. Swap mayonnaise for Greek yogurt to lighten the dish and add a bit of tang.
Serving Suggestions
Pair with a warm bowl of tomato soup for classic cozy vibes. Serve alongside crispy fries or chips for a crunchy contrast. Add a fresh green salad with a lemon vinaigrette to brighten the meal.
