01 - Preheat oven to 350°F.
02 - Slice Hawaiian rolls horizontally, keeping them attached to each other rather than separating into individual rolls.
03 - Place bottom halves in a baking dish or on a lined baking sheet. Lay one cheese slice on each roll bottom, overlapping as needed for even coverage.
04 - Replace the tops of the rolls over the cheese layer.
05 - In a small bowl, whisk together melted butter, garlic powder, dried parsley, and salt until well combined.
06 - Brush the butter mixture generously over the tops of all rolls.
07 - Bake for 12 to 15 minutes until cheese is fully melted and tops are golden brown.
08 - Remove from oven and let cool slightly. Cut into individual sandwiches and serve warm.
