Preheat the oven to 350°F. Then lightly spray a 9x13 glass or ceramic baking pan with nonstick baking spray.
Remove the Hawaiian rolls from the bag in one large piece (don't pull them apart). Using a long serrated knife, cut the rolls in half, being careful to keep them all intact. Place the bottom set of buns into the prepared pan. You might have to press them in gently to make them fit.
24 pack Hawaiian rolls
Layer the cheese on the rolls, allowing it to overlap and completely cover the bread. Layer the pastrami on top of the cheese in an even layer. Then place the top rolls back on top.
12 slices swiss cheese, 1 lb thinly sliced pastrami
In a small bowl, combine the topping ingredients together. Brush the rolls evenly with the topping. Then bake for 15-20 minutes, until the cheese is melty, the meat is warmed through, and the buns are toasted.
4 tablespoon butter, 2 teaspoon worcestershire, 1 teaspoon poppy seeds, 1 teaspoon dried parsley, ½ teaspoon garlic powder, ¼ teaspoon kosher salt
While they bake, pour the dressing over the coleslaw and toss until well combined. When the sliders are finished baking, remove the top rolls carefully and layer on the coleslaw. Replace the tops, then use a sharp knife to slice. Serve immediately.
4 cups shredded coleslaw, ½ cup hot honey mustard dressing
