01 - Preheat your oven to 350°F.
02 - Slice the Hawaiian rolls in half horizontally, keeping the rolls attached to each other without separating into individual rolls.
03 - Place the bottom halves of the rolls in a baking dish or on a lined baking sheet. Lay one slice of cheese on each roll bottom, overlapping as needed to cover evenly.
04 - Place the tops of the rolls back on to close the sandwiches.
05 - In a small bowl, combine melted butter, garlic powder, dried parsley, and salt until well blended.
06 - Brush the butter mixture generously over the tops of the rolls using a pastry brush.
07 - Bake for 12–15 minutes until the cheese is melted and the tops are golden brown.
08 - Remove from oven, let cool slightly, then cut into individual sandwiches. Serve warm.
