15-Minute Classic Tuna Melts

1.Prepare the tuna salad: In a medium bowl, combine the drained tuna, mayonnaise, chopped celery, minced red onion, Dijon mustard, black pepper, and salt. Mix thoroughly until well combined and creamy.

2.Assemble the sandwiches: Lay out the four slices of bread. Distribute the tuna salad evenly across two slices of bread. Top each portion of tuna salad with two slices of cheese, then cover with the remaining two slices of bread.

3.Butter the exterior: Spread half of the softened butter evenly on the outside of one sandwich (one side of the top slice and one side of the bottom slice).

4.Grill the first sandwich: Heat a non-stick skillet or griddle over medium heat. Place the first sandwich, butter-side down, onto the hot skillet. Spread the remaining butter on the upward-facing side of the sandwich.

5.Cook until golden: Grill for 3 to 4 minutes per side, pressing down gently with a spatula occasionally, until the bread is golden brown and crispy and the cheese is completely melted and gooey.

6.Repeat and serve: Remove the first melt from the skillet, slice in half diagonally, and repeat the grilling process with the second sandwich. Serve immediately.
