This Tuna Melt Sandwich recipe delivers a warm, satisfying, and easy-to-make classic. Flaked tuna is combined with creamy mayonnaise, tangy Dijon mustard, and a touch of crisp celery and onion for texture.
In a bowl, mix drained tuna, mayonnaise, Dijon mustard, diced celery, red onion, chopped dill pickles, and season with salt and pepper to your preference.
Spread the tuna mixture evenly onto 2 slices of bread.
Layer each with a slice of cheddar cheese.
Arrange the bread slices on a baking sheet and broil on low heat until the cheese is melted and bubbly, about 2-3 minutes.
Take out from the oven and cut the sandwiches in half.
Optionally, pair with chips when serving.
Notes
For extra crunch, toast the bread slightly before assembling the sandwiches. This helps prevent sogginess and adds a satisfying crisp texture.
