Crush the garlic through garlic press into a small bowl and mix it with a spoonful of olive oil. Toast the sliced bread and pour the garlic oil on it. Place the soup in the bowls and sprinkle with grated Gruyère. Serve with the garlic toasts. (If you want to be very proper, cut the bread into smaller pieces, put them on top of the soup, then cover with grated Gruyère cheese and bake in the oven for a few minutes until the cheese is melted)
