I might be the weird one but I grew up eating garlic toast made this way. If you toast the bread, it can work as a grater when you rub the garlic on it, then you put some butter or olive oil on it and you got a quick garlic bread.To be fair Jamie Oliver does this too I've seen a number of his videos where he suggests rubbing garlic on the bread to give it a garlic taste. Never done it myself but it must work if Jamie Oliver does it!
