Salad can be a great healthy meal. If you don't want the calories and fat that come with a heavy dressing, try using bread as a thickening agent. You'll get a rich, creamy texture without using eggs or mayo to get it. This is especially useful if you're out of eggs, have an egg allergy, or are a vegan.
You don't have to change your dressing recipe to make this work -- just use bread where you would normally use a thickener like mayo or egg yolk. As you blend the bread with the rest of the ingredients, the dressing will thicken.
You can use this as an opportunity to get rid of bread that is leaning towards stale. If you need ideas on what kind of salad to use this dressing on, check out this infographic (use it in place of creamy lemon dressing) or hit the full post linked below for a complete recipe.
