Bring a large saucepan of lightly salted water to a boil. Cook macaroni 8 to 10 minutes or until al dente. Drain and rinse under cold water.
In a large bowl, mix the macaroni, celery, sweet onion, roasted peppers and gherkin. In a separate bowl, mix the salad dressing, mustard, vinegar, sugar and salt. Stir dressing into the macaroni mixture. Fold in the eggs. Chill in the refrigerator at least 2 hours before serving.
