No matter what kind of bread we use (this is even really good on the wheat hoagie rolls from Sam's Club) we always season our garlic bread this way...
Butter bread generously.
Sprinkle with granulated garlic to taste.
Lightly sprinkle with paprika.
Crush dried parsley over the bread.
Top with parmesan to taste.
Place under broiler for about 5 minutes, or until lightly browned, watching continuously (trust me).
Make LOTS because there will never quite be enough!
