This is so easy and such a nice alternative when you forget to buy garlic bread or on the spur of the moment decide to have garlic bread.
You can also use regular slice bread as well although the other is my preferance.
For those that don't have acccess to an oven you can also use a skillet to brown the bread and make it mnore as a country toast garlic bread.
For skillet follow directions to make the bread place in a skillet buttered side down and put a weight on top ( I usually use a plate) on a lower heat setting jut let cook until brown. If you want you can do the same to the oopisite side but for garlic bread that is almost overkill.
