  • 12–12½ ounces White Albacore Tuna in Water drain if in a can – do not drain if in a pouch
  • 2 tablespoons Finely Diced White Onion about half of a very small onion
  • 2 tablespoons Finely Diced Celery about half of a celery rib, plus extra to serve on the side if desired
  • 2 ounces Cream Cheese softened
  • 2 tablespoons Mayonnaise
  • ½ teaspoon Yellow Mustard
  • ¼ teaspoon Salt
  • ¼ teaspoon Black Pepper
  • 4 Croissants for serving
  • 1–1½ cup Shredded Lettuce for serving
  • 2 Apples cored and sliced thin, for serving


  • If you’re using pouch tuna there is no need to drain it. If you’re using canned tuna, drain it but don’t leave it bone-dry.
  • Stir the tuna with a fork, pressing down and breaking up any chunks.
  • Dice the onions and the celery as finely as possible.
  • Add the tuna, onion, celery, cream cheese, mayonnaise, mustard, salt and black pepper to a large bowl. Stir the ingredients well until combined.
  • Taste the tuna salad and add salt, if needed. As a reference, we added a pinch of salt to ours.
  • Cover the bowl and refrigerate until the tuna salad is chilled.

  • Add about ¼ of the tuna salad to a croissant. Top with shredded lettuce and serve with the apple slices in the sandwich or on the side.
