This classic tuna melt has been a family favorite for years and always hits the spot when I need a fast meal.

Ingredients

• Tuna Salad: 1 can (5 oz / 140 g) tuna, drained, 2 tbsp mayonnaise, 1 tsp Dijon mustard, 1 stalk celery, finely chopped, 1 tbsp red onion, finely chopped, 1 tsp lemon juice, salt and freshly ground black pepper, to taste
• Sandwich: 4 slices sandwich bread (white, whole wheat, or sourdough), 4 slices cheddar cheese (or Swiss), 2 tbsp unsalted butter, softened

Instructions

Mix Tuna Salad:

In a bowl, mix together the drained tuna, mayonnaise, Dijon mustard, celery, red onion, lemon juice, salt, and pepper until well combined.

Assemble Sandwich:

Lay out the bread slices. Spread the tuna salad evenly over two slices. Top each with two slices of cheese.

Form Sandwich:

Cover with the remaining bread slices to form sandwiches.

Butter Bread:

Butter the outsides of each sandwich (one side per slice).

Heat Pan:

Heat a nonstick skillet or griddle over medium heat.

Cook Sandwiches:

Place the sandwiches buttered side down on the skillet. Cook for 3–4 minutes, pressing gently, until golden brown.

Flip:

Flip and cook the other side for another 3–4 minutes, until the bread is golden and the cheese is melted.

Serve:

Remove from skillet, slice in half, and serve hot.

My kids love sitting around the kitchen table enjoying these sandwiches fresh off the skillet.
