Ingredients:

  • 1 (5 ounce/142g) can tuna in water, drained well
  • 2 tablespoons (30 ml) mayonnaise (full-fat or light)
  • 1 teaspoon (5 ml) Dijon mustard
  • 1/4 teaspoon (about 1/2 ml) smoked paprika
  • 1 tablespoon (15ml) finely chopped celery (optional)
  • Salt and freshly ground black pepper to taste
  • 2 slices sourdough bread
  • 2 tablespoons (30g) unsalted butter, softened
  • 2-3 slices (approximately 2 ounces/56g) sharp cheddar cheese

Instructions:

  1. In a small bowl, combine the drained tuna, mayonnaise, Dijon mustard, smoked paprika, and celery (if using). Season with salt and pepper to taste. Mix well.
  2. Spread softened butter evenly on one side of each slice of sourdough bread.
  3. Place one slice of bread, butter-side down, in a frying pan or on a griddle over medium heat. Top with the cheddar cheese slices, then spread the tuna mixture evenly over the cheese. Top with the remaining slice of bread, butter-side up.
  4. Cook for 3-5 minutes per side, or until the bread is golden brown and the cheese is melted and gooey. Use a spatula to gently press down on the sandwich while cooking to ensure even browning.
  5. Remove from the pan, slice in half, and serve hot.
