Toast your slices of bread. You can use a Toaster if you like more crispy.
Brush a little olive oil or butter over one side of the toasted bread. You can do this to other site of bread if you like more olive oil on your slices.
Cut a garlic clove in half, on the diagonal. Gently rub the cut side of the garlic clove over the olive oil-brushed toasted bread.
