Cook the elbow macaroni in salted water according to the package instructions until it is aldente - it should be tender but firm to the bite. Drain and rinse the pasta under cold water to stop the cooking process and set it aside.
In a separate bowl, combine all the dressing ingredients together and whisk until smooth and creamy.
Place the macaroni into a large bowl. Add the diced bell peppers, red onion, celery, eggs, and any other desired mix-ins*.
Pour in the dressing and stir to combine. Garnish with parsley if desired and serve right away or cover and refrigerate until ready to serve.
