I got this from a TOH booklet. I have not tried it yet but I don't want to lose the recipe. It's got ham, eggs, cheese, veggies and more. It could be a meal. Prep time includes chilling time. I think you could easily add more veggies if you prefer.
In a saucepan combine the eggs, sugar, vinegar and salt. Cook and stir over low heat for 10 minutes or until mixture is thickened and a thermometer reads 160 degrees. Cool completely, stirring several times.
In a bowl combine the macaroni, hard cooked eggs, ham, cheese, celery, onion, pickle relish and olives. Stir mayonnaise into cooled egg mixture and pour over the macaroni mixture. Stir to coat. Cover and refrigerate for at least 2 hours.
