Ingredients
  

Tuna Salad Mixture:

  • 3 5 oz cans albacore tuna (packed in water), drained well
  • ¼ cup plus ½ tablespoon mayonnaise vegan or regular
  • 3 tablespoons celery finely chopped
  • 2 tablespoons unsweetened dill pickle relish
  • 1 teaspoon Dijon mustard
  • ½ to ¾ teaspoon sea salt or to taste
  • Pinch black pepper

For Serving:

  • Large lettuce leaves e.g., Romaine hearts, Butter, or Iceberg

Optional Toppings:

  • 1 large avocado diced
  • 12 grape tomatoes halved

Instructions
 

  • Prepare Lettuce: Carefully separate, wash, and thoroughly pat dry several large lettuce leaves suitable for forming cups. Choose leaves that are crisp and sturdy. Set them aside.
  • Mix Tuna Salad: In a medium bowl, flake the thoroughly drained tuna with a fork into bite-sized pieces. Add the mayonnaise, finely chopped celery, unsweetened dill pickle relish, Dijon mustard, sea salt (starting with ½ teaspoon and adding more if needed), and black pepper. Stir well with a spoon or fork until all ingredients are evenly incorporated.
  • Assemble Cups: Lay out the prepared lettuce leaves on individual plates or a serving platter. Spoon a portion of the prepared tuna salad mixture neatly into the center of each lettuce cup.
  • Garnish and Serve: Just before serving, garnish the filled lettuce cups with the diced avocado and halved grape tomatoes, if using. Serve immediately for best results.
