Fancy Tuna Melt

A fancy tuna melt is definitely the best kind of tuna melt. Swiss (or Gruyere) cheese, cucumber, tomato, and a splash of lemon juice, all served on a warm baguette. This isn't your Mama's tuna sando.

Ingredients

  • 9 ounces canned tuna, (preferably packed in oil), drained
  • 1/3 cup store-bought or homemade mayonnaise
  • 1/2 celery stalk, finely sliced
  • 1/4 small (about 2 tablespoons) red onion, finely chopped
  • 1/4 medium (about 2 inches [5 cm] long) cucumber, peeled, if desired, and finely diced
  • Juice of 1/2 lemon
  • Sea salt and freshly ground black pepper to taste
  • 1/2 baguette, cut crosswise into 2 portions, or 4 slices bread, such as sourdough or multigrain
  • 4 slices tomato, (optional)
  • 2 slices cheese of your choice, such as Gruyère, Swiss, or white Cheddar

Instructions

  • Preheat the oven to 400°F (204°C).
  • Using a fork, flake the tuna into a bowl. Stir in the mayonnaise, celery, onion, cucumber, and lemon juice and mix well. Season with salt and pepper to taste and mix again.
  • Cut the baguettes in half lengthwise and divide the tuna mixture between the bottom pieces. Place 2 slices tomato on each sandwich, if desired. Top with a cheese slice and the baguette lids, pressing down gently to settle the filling.
  • Place the sandwiches on a baking sheet and bake for 5 to 7 minutes, until the sandwich is warmed through and the cheese begins to melt and turn ooey gooey. Alternatively, you can warm the sandwich in a griddle or sandwich maker.
  • Serve the sandwiches immediately, preferably with napkins galore. Originally published April 15, 2013.
