Changes and Hints
You may make it more flavorful by adding cooked and crumbled bacon or chopped hard-boiled eggs for a change of pace. To change up the texture of the dressing, some people prefer to add shredded cheddar cheese or a combination of sour cream and mayonnaise. Use low-fat mayonnaise or a combination of Greek yogurt and mayonnaise for a lighter version.
