Ingredients

Scale
  • 1 (12 count) package Hawaiian sweet rolls
  • 12 slices ham
  • 12 slices salami
  • 12 slices pepperoni
  • 1214 slices provolone cheese
  • 1/4 cup mayonnaise
  • 1 tablespoon red wine vinegar
  • 1 tablespoon olive oil
  • 1 tablespoon pepperoncini juice
  • 2 teaspoons Italian seasoning
  • 1/2 teaspoon salt
  • 1/4 teaspoon black pepper
  • 1/2 cup shredded iceberg lettuce
  • 1/4 cup thinly sliced red onion
  • 1/3 cup sliced pepperoncini peppers
  • 2 1/2 tablespoons unsalted butter, melted
  • 2 cloves garlic, minced
  • 1 teaspoon Italian seasoning (for glaze)

Instructions

  1. Preheat your oven to 350 degrees Fahrenheit. Lightly grease a 9×13 inch baking dish.
  2. In a small bowl, combine the mayonnaise, red wine vinegar, olive oil, pepperoncini juice, 2 teaspoons of Italian seasoning, salt, and pepper. Mix well to create the dressing base.
  3. In a separate medium bowl, combine the shredded lettuce, sliced red onion, and sliced pepperoncini peppers. Pour the dressing base over the vegetables and toss gently until everything is coated. Set this grinder salad mixture aside.
  4. Slice the entire package of Hawaiian rolls horizontally, keeping the rolls connected. Place the bottom half of the rolls in the prepared baking dish.
  5. Layer the ingredients over the bottom rolls: place the ham slices evenly, followed by the salami, pepperoni, and then the provolone cheese slices.
  6. Place the top half of the rolls over the cheese layer.
  7. In a small bowl, melt the butter. Stir in the minced garlic and 1 teaspoon of Italian seasoning. Brush this garlic butter mixture evenly over the top of the slider buns.
  8. Cover the baking dish tightly with aluminum foil. Bake for 15 minutes.
  9. Remove the foil and bake for another 5 to 7 minutes, or until the cheese is fully melted and the tops are lightly golden brown.
  10. Carefully remove the sliders from the oven. Lift the top layer of rolls and spoon the prepared grinder salad mixture evenly over the melted cheese layer. Replace the top rolls.
  11. Slice the sliders into individual portions. Serve immediately while warm.

Notes

  • For extra flavor, you can add a layer of thinly sliced deli turkey along with the ham, salami, and pepperoni.
  • If you prefer a spicier kick, substitute banana peppers with thinly sliced jalapeños in the salad mixture.
  • These sliders are best served warm right after baking and topping with the salad mixture.
