A decent mayo dressing is a must. Mac, vegetables as you want but I do think onions celery carrots mandatory. Peppers radishes herbs jicama, pickle your choice. But get a good mayo dressing..

1 lb. elbow macaroni, finely chopped celery and red onion, Hellman's mayonnaise, 1 can sweetened condensed milk, finely chopped peppers,( I use red, yellow and orange) and salt and pepper. I made this recipe up because my family doesn't like macaroni salad. They LOVE it! Now I have to make it for all the potlucks!
