There's something extra-special about a deli macaroni salad, and I believe the trick here is in marinating the macaroni before adding the other ingredients. Although it sounds quite basic, oftentimes simplicity produces marvelous results, and this recipe is no exception. With the warmer months upon us and barbecues and gatherings sure to be plentiful, this mac salad will be a wonderful addition. (Though I love having it all year round.) Feel free to add diced celery or onion, or any other goodies you enjoy in your macaroni salad -- it's yours for the making!
