Method

Fish Filling Preparation

  1. 1

    Drain and Flake the Tuna

    Open the canned tuna and drain the liquid. Use a fork to flake the tuna into smaller pieces in a mixing bowl.

  2. 2

    Combine Ingredients

    Add mayonnaise, finely chopped celery, red onion, Dijon mustard, lemon juice, salt, and black pepper to the flaked tuna. Mix until well combined.

  3. 3

    Taste and Adjust Seasoning

    Taste the tuna mixture and adjust seasoning if necessary, adding more salt or pepper to taste.

Grinder Assembly

  1. 4

    Prepare the Rolls

    Slice the submarine rolls lengthwise, ensuring not to cut all the way through. This creates a pocket for the filling.

  2. 5

    Layer the Ingredients

    Spread a generous amount of the tuna filling into each roll. Top with a layer of romaine lettuce, slices of tomato, and pickles.

  3. 6

    Close and Serve

    Close the rolls gently and serve immediately. Optionally, you can wrap them in parchment paper for easier handling.
