This recipe is from Delia's Complete Cookery Course.
Begin by drizzling the olive oil onto a large solid baking sheet, add the crushed garlic then, using either your hands or a piece of kitchen paper, spread the oil and garlic over the baking sheet.
Now place the bread slices on top of the oil, then turn each one over so that both sides have been lightly coated with the oil. Bake them in the oven for 20-25 minutes (but do use a timer because a few minutes too long and they will be over-done). You can make these a day ahead, and store in an airtight tin once they have cooled.
