I like to use the white bread for my garlic bread.
I just lay the bread onto aluminum foil, as many pieces as you'd like.
I like it very buttery. I layer butter first, as much as you desire, and the type of butter you like best. I then put a thick layer of garlic powder. I personally love Goya's garlic powder. I then layer mozzarella cheese all over the top. I like them very cheesy, add cheese to your liking.
