MELTED MARGARINE

Preheat the oven to 400 degrees F (200 degrees C). Line a rimmed baking sheet with parchment paper.

Stir Parmesan cheese, garlic powder, and basil together in a small bowl.

Place hot dog buns, cut-sides up, onto the prepared baking sheet. Spread margarine onto buns, then sprinkle Parmesan mixture over top.
