Ingredients

For The Tuna Filling

  • 12-16 oz canned tuna drained
  • 1/2 cup diced celery
  • heaping 1/2 cup mayo
  • 1 tbsp dill pickle relish
  • 1/4 tsp celery salt
  • pepper to taste

For The Sliders

For The Sauce

  • 1 stick butter
  • 2 tbsp dried minced onion
  • 1 1/2 tsp Worcestershire sauce
  • 1/2 tsp dried dill
  • 1/4 tsp garlic powder

Instructions

To Make The Tuna Filling

  • Add the tuna to a large mixing bowl, and use a sturdy fork to flake it apart.
    12-16 oz canned tuna
  • Add all of the remaining filling ingredients to the bowl. Stir together until evenly combined.
    1/2 cup diced celery, heaping 1/2 cup mayo, 1 tbsp dill pickle relish, 1/4 tsp celery salt, pepper

To Assemble The Sliders

  • Carefully remove the cut top half of the buns, and set aside. Arrange the bottom buns in a greased 8x8" baking dish.
    1 16 count pkg sweet Hawaiian rolls
  • Spread the tuna mixture evenly out over the bottom buns.
  • Place the tomato slices followed by the slices of cheese evenly out overtop.
    thinly sliced tomatoes, 6 slices Havarti cheese
  • Carefully place the top half of the buns on, lining up as needed to fit correctly.

To Make The Sauce

  • Melt the butter in a skillet over medium low heat. Once melted whisk in the remaining sauce ingredients until combined.
    1 stick butter, 2 tbsp dried minced onion, 1 1/2 tsp Worcestershire sauce, 1/2 tsp dried dill, 1/4 tsp garlic powder
  • Pour the butter sauce evenly out over the assembled sandwiches.
  • Cover the sliders with foil, and refrigerate for 1-2 hours.
  • Bake the sliders, covered still, at 350° for 25 minutes.
  • Carefully uncover the sliders, and then bake for another 5 minutes- just until golden brown and crispy on top.
  • Slice & serve the sliders while still warm.

Notes

  • Don’t leave the assembled sliders in the fridge for longer than 2 hours prior to baking. 
  • Feel free to omit the tomato slices if you don’t like tomato.
  • If you hate celery, you can skip it in the tuna.
