Slice the bread about ½ inch thick and brush both sides with virgin olive oil. Grill or broil the bread until it is marked on both sides and somewhat crisp. Immediately rub the bread with a cut clove of garlic and eat.
As a variation you may rub the garlic bread with a cut tomato or cover it with finely chopped tomato and sprinkle with freshly ground pepper. This is a little messier to eat, but it is really delicious and worth the risk of a few specks of tomato on your shirt.
