Our Hawaiian Ham and Cheese sliders have a magical mayo sauce that sets them apart from all the rest. Use any ham you have on hand, and enjoy a finger-licking-good meal that's ready in just 20 minutes!
Preheat oven to 350°F and lightly grease a 9x13-inch pan.
Prepare the Magical Mayo Sauce in a small bowl by whisking together 1/2 cup mayonnaise, 1/2 teaspoon salt, 1/2 teaspoon black pepper, and 1/2 teaspoon garlic powder.
Cut the entire 12 count package Hawaiian rolls half, separating it into two slabs. Spread the mayo sauce evenly over the bottom slab.
Layer half of the 12 ounces Swiss cheese slices on the bottom slab, followed by 1 pound sliced ham, and then the remaining cheese. Top with the other slab of rolls and place the assembled sandwiches in the prepared pan.
In another small bowl, whisk together 1/2 cup melted butter, 1 tablespoon poppy seeds, 1 tablespoon Dijon mustard, 1 tablespoon onion powder, and 1 teaspoon Worcestershire sauce to make the butter sauce.
Drizzle the butter sauce evenly over the top of the sandwiches.
Loosely cover the pan with aluminum foil and bake for 10 minutes or until the cheese is completely melted. Serve hot.
