Ingredients

  • 3 (5-ounce) cans tuna drained
  • ½ cup mayonnaise plus 1-2 tbsp if needed
  • 3 tablespoons celery finely chopped
  • 2 tablespoons red onion minced
  • 2 tablespoons dill pickles minced (or use sweet relish, see notes)
  • 2 teaspoons pickle juice or lemon juice/pepperoncini juice
  • ¼ teaspoon garlic powder
  • ¼ teaspoon kosher salt
  • ¼ teaspoon black pepper
  • focaccia bread slices or tortilla, for serving
  • 1 large avocado sliced
  • lettuce or baby spinach as needed

Instructions

  • TUNA: Drain the liquid from the tuna. To make an extra smooth tuna salad, you can pulse the tuna and mayonnaise in a food processor. This makes a mousse-like salad. I typically skip this.
  • MIX: In medium bowl, combine the tuna, mayonnaise, celery, red onion, minced pickles, pickle juice, garlic powder, kosher salt, and black pepper. Taste and adjust with more salt as desired, this will vary depending on the amount of salt in your tuna. If time permits, let the tuna salad hang out for 10 minutes; this allows the flavors to develop a bit more – totally optional though!
  • TOAST: Toast the bread or heat the tortilla if making a wrap. Add baby spinach, lettuce and avocado slices as desired. Scoop tuna on top one side and top with the second slice of bread. Serve!

Notes

  • Additional Add-ins: Feel free to play around with this! Sometimes I'll add a squeeze of jalapeño mustard/dijon or even a sprinkle of red pepper flakes. You can use lemon pepper seasoning/ pizza seasonings etc. Traders pickle seasoning is what I'm planning on trying next!
  • Pickles: Sometimes I’ll swap the dill pickles for bread and butter, or even use hot and sweet pickled jalapeños! You can play around with the mix-ins a bunch for this recipe!
  • Bread not included in nutrition values
