Cut the black bread into 1/2 inch (1.25 centimeter) strips.
In a wide saucepan, pour a thin layer of sunflower/vegetable oil about 1/2-1 inch (1.25-2.5 centimeters) deep and place over medium low heat.
Cover a large plate with a paper towel. Set aside.
Once the oil is thoroughly heated, add a few black bread strips in a single layer.
Fry, turning occasionally, until all sides are deeply golden and the edges are crisp. Transfer to the towel-lined plate and repeat with remaining batches.
Place the fried bread pieces in a large bowl while still warm and gently toss with the crushed garlic, rubbing the garlic into the sides of the bread, and a sprinkling of salt until evenly coated.
