What you will need

This recipe uses 6 simple ingredients that you can find at any grocery store:

  • 2 cans chunk light tuna in water drained
  • 3 tablespoons mayonnaise
  • 8 slices white or wheat sandwich bread
  • 4 slices American or cheddar cheese
  • 1 teaspoon yellow mustard
  • 0.25 teaspoon salt and pepper to taste

Step by step instructions

Step 1: Make the Tuna Salad

In a medium bowl combine drained tuna mayonnaise mustard salt and pepper. Mix well until creamy and fully combined. Taste and adjust seasoning as needed.

Step 2: Toast the Bread

Toast all 8 bread slices in a toaster or under the broiler until lightly golden. This prevents the bread from becoming soggy once the tuna is added.

Step 3: Assemble and Melt

Spoon the tuna mixture generously onto 4 toast slices and spread evenly. Top each with one slice of cheese. Place under the broiler for 2 to 3 minutes until the cheese is melted and slightly bubbly.

Step 4: Top and Serve

Place the remaining toast slices on top to complete the sandwiches. Cut diagonally and serve immediately while the cheese is still warm and gooey.

  • mayonnaise → Greek yogurt for a lighter and tangier tuna salad
  • white bread → English muffins or sourdough for extra crunch

Common mistakes to avoid

Watch out for these pitfalls that can affect your results:

  • Not draining the tuna well enough which makes the tuna salad watery and soggy
  • Broiling too long which burns the cheese instead of melting it smoothly
