Preheat oven to 350°F and line a baking sheet with parchment paper if desired.
In a small bowl, mix softened butter, garlic powder, dried oregano, and parsley until well combined.
Slice each Hawaiian roll vertically into thirds.
Spread the garlic butter mixture evenly over the cut sides of the rolls.
Layer cheddar cheese between the rolls, ensuring the cheese covers the bread for an even melt.
Arrange sliders on the baking sheet and bake for 20–25 minutes, flipping halfway through, until golden brown and melted.
Serve warm with tomato soup, marinara sauce, or your favorite dip.
