Adaptations and Hints
For a variation, you might add chopped hard-boiled eggs or cooked and crumbled bacon to enhance the taste. Some like to add shredded cheddar cheese or a sour cream and mayonnaise combo to switch up the dressing’s texture. For a lighter version, use reduced-fat mayonnaise or a blend of Greek yogurt and mayonnaise.
