Cook the macaroni in a saucepan with enough cold water to cover it by about half an inch.
Add a pinch of salt, and bring to a boil over medium-high heat.
Stir frequently to prevent sticking.
Once cooked, drain and rinse with cold water.
In a large bowl, whisk together mayonnaise, cider vinegar, mustard, sugar, salt, pepper, and garlic powder until smooth.
This creates the creamy dressing that ties everything together.
Add the cooled macaroni to the bowl with the dressing.
Toss until the macaroni is thoroughly coated.
Make sure each piece of pasta absorbs the delicious flavors.
Incorporate diced celery, sweet gherkins, red bell pepper, parsley, and green onions.
Stir gently to maintain the texture and freshness of the vegetables.
Store the completed salad in the refrigerator for at least an hour.
This allows the flavors to meld and enhances the taste.
You can serve it cold for the optimal experience.
