Preheat the oven to 350°F (175°C). Line a baking sheet with parchment paper if desired.
In a small bowl, mix the softened butter, garlic powder, oregano, and parsley to make garlic butter.
Slice each Hawaiian roll into thirds vertically.
Spread the garlic butter evenly on the cut sides of the rolls.
Layer cheddar cheese between the rolls, making sure the cheese covers the bread for an even melt.
Arrange the sliders on the prepared baking sheet. Bake for 20–25 minutes, flipping halfway through, until golden and melty.
Optional: Broil for 30–60 seconds at the end for a crispier top—watch carefully.
Serve warm with tomato soup, marinara sauce, or your favorite dip.
