Do a slice of toast making sure it is crisp. Have a clove of garlic peeled and ready and just rub the clove across the bread. It has a grater effect and vanishes into the bread. Then dip a clean flat blade knife into a bottle of oil and lightly smear across. Add black pepper and a bit of fresh finely chopped parsley if you have any. I suppose you could use spray oil which is very low. If your oven is on the go, pop it in for a minute to crisp back up. Yum !
