Cut the sub rolls in half and place on a baking sheet.
Melt the butter in the microwave (on defrost) in a glass container.
Once the butter is melted, add 1/2 teaspoon garlic powder, 1/2 teaspoon Italian Seasoning, and if you like, a dash of salt. Mix thoroughly.
Next, spread the butter mixture onto the top of each sub roll.
Sprinkle cheese on top of each roll (optional).
Broil the bread on high for 1-2 minutes. For best results, watch the bread carefully as it can burn very quickly.
Notes
I did not line my baking sheet, but if you like, you can use foil. Do not line your baking sheet with parchment paper. It can ignite on the broiler setting.
