  • 20 ounces tuna in water or oil, drained (four 5-ounce cans)
  • 1 medium onion, chopped (about ½ cup)
  • ½ celery stalk, chopped (about ¼ cup)
  • 1 clove garlic, minced (or ½ teaspoon ready minced garlic)
  • 1 tablespoon parsley, chopped
  • 5 tablespoon mayonnaise
  • 3 tablespoon olive oil, divided
  • ½ cup mozzarella, shredded
  • salt and pepper, to taste
  • 12 slices bread
  • softened butter


  • Drain the water or oil from the tuna.
  • Place the tuna in a medium bowl and using a fork loosen it apart.
  • To the tuna bowl add the onion, celery, garlic, parsley, mayonnaise, 2 tablespoons olive oil, and mozzarella cheese. Stir to combine.
  • Salt and pepper to taste and mix again.
  • Place a nonstick skillet on the stove and add 1 tablespoon olive oil. Heat over medium heat.
  • Butter one side of a piece of bread and carefully place that slice butter side down into the now hot skillet.
  • Now spoon about 3 heaping tablespoons of tuna filling onto the slice of bread in the skillet, more or less depending on how thick you like your sandwiches.
  • Now take another slice of bread and butter one side. Place that slice of buttered bread on top of the sandwich in the skillet with the butter side up.
  • Watch for browning on the underside of the sandwich and grill until golden brown. Next flip the sandwich over and brown the other side.
  • Remove from the skillet and place on a paper towel lined plate.


Note: You can place the tuna in a paper towel or a clean dish towel and wring out even more liquid, this makes for a less soggy sandwich.
Note: If your butter is too hard to spread, place it in the center of the frying pan. When it has fully melted, spread it around a little and set your bread directly on top.
