Bring a large pot of lightly salted water to a boil.
Add the macaroni, and cook until tender, about 8 minutes.
Rinse under cold water and drain.
In a large bowl, mix together the mayonnaise, vinegar, sugar, mustard and House Seasoning Blend. Stir in the onion, celery, green pepper, carrot, celery seed and macaroni.
Gently fold in chopped eggs.
Refrigerate for at least 4 hours before serving, but preferably overnight.
Christina's Notes
Cool : Warm pasta absorbs too much dressing and can become sticky.
Seasoning: Cold foods need more seasoning for balanced flavor.
Dressing: Save a small amount to stir in before serving if the salad thickens overnight.
Dice Evenly: Smaller vegetable pieces create a more balanced bite.
Chill: A few hours in the refrigerator improves texture and flavor.
