Dunkley's Famous Macaroni Salad

For large gatherings, I think this salad would go over great! This is one of the best tasting macaroni salads I have ever had! I know there are a lot of ingredients, but don't skimp. The flavor sensation is absolutely incredible!! I saw this on Food Network's 'Calling All Cooks', and got the recipe from the website. This recipe serves about 25 people. NOTE: The ORIGINAL recipe calls for 1-2 Tbsps. garlic salt, and that's the way I entered the recipe. If you are salt sensitive, I suggest you use less. You can always add more.
