Classic Macaroni Salad

1. In a large pot, bring water to a boil and add the macaroni. Cook it for 8-10 minutes or until it's al dente. Then, drain the macaroni in a colander and rinse it with cold water to stop the cooking process.
2. While the macaroni is cooling, in a bowl, mix together the mayonnaise, sweet pickle relish, vinegar, mustard, salt, and pepper. This will be your salad dressing.
3. In a large bowl, add the cooled macaroni, diced red bell pepper, celery, onion, and green onions. Then, add the prepared dressing and mix well so that all the ingredients are evenly coated with the dressing.
4. Cover the bowl and refrigerate for 1-2 hours before serving. This will allow all the ingredients to soak up the dressing and give the salad a rich flavor.
5. Before serving, give the salad another good stir. If you want, you can add some more fresh green onions for garnish.

And that's it! Your Classic Macaroni Salad is ready to be served. This recipe is easy to modify by adding other ingredients to taste, such as boiled eggs, tuna, or chicken. Enjoy your meal!
