Macaroni Salad

Ever since I can remember, I have loved my best friend's mom, Mrs. Swete's macaroni salad. So much so that now when I go home for visits, she will set aside a special batch just for me! I believe she enjoys the fact that her recipe is a best kept secret, because I have asked multiple times for it and she always has a way of skirting the topic.
So...I recently began my quest for a macaroni salad recipe that might just resemble hers. I don't know if it was beginner's luck, but the flavor of this one is almost identical! And major bonus was a huge thumbs up from my husband! The only thing I will add next time that I believe is missing is sliced black olives and it may just be a good substitute until my next visit home for the "real thing" :).

• 2 cup mayo
• 4 tbs. vinegar
• 2 tbs mustard
• 2 tsp sugar

Mix all ingredients in a large bowl and refrigerate
