Rich and buttery, these Hawaiian sliders are filled with thinly sliced ham and melty Swiss cheese, all sandwiches between a sweet Hawaiian roll and topped with a seasoned butter mixture. These are perfect for a quick dinner, but we most often serve them at parties and get togethers. It never hurts to double the recipe because these go quick!
Slice all of the rolls in half and place the bottom halves in a 9x13 baking dish.
Place ham and cheese on the bottom of the sliced rolls. Cover with the top half of roll.
Mix together the remaining five ingredients in a small bowl and spoon over the tops of the sandwiches.
Cover tightly with foil and refrigerate anywhere from 1 to 24 hours.
Bake, covered, in a pre-heated oven at 350 for 25 minutes.
Serve warm.
Notes
The nutrition information is based on 1 sandwich, but we find that most people eat 2 to 3 of these sliders. If you have onion haters, we've found that swapping the minced onion for 1 teaspoon of onion powder is a good compromise.
