A common misconception is that bread is fattening. But bread is a carbohydrate, and a gram of carbohydrate provides the same calories as protein: four per gram. It's the fat you add to bread that drives up the calories.
Here is a garlic-bread topping that is exceptionally low in fat because we use low-calorie margarine and cut the amount used by half. We also go lightly on the cheese and spruce up the flavor with herbs.
2 tablespoons low-calorie margarine
1 clove garlic, pressed
1 teaspoon fresh lemon juice
6 slices French bread, toasted on 1 side
1 tablespoon grated Romano cheese, optional
1 tablespoon chopped rosemary or parsley
