Cook macaroni in salted water according to directions on package (I added about 1/2 tbsp salt to the water).
Drain and rinse with cold water until completely cool. Let drain very well.
In a medium mixing bowl stir together mayonnaise, Greek yogurt, vinegar, mustard, honey, and season with salt and pepper to taste (start with about 1/2 tsp salt and 1/4 tsp pepper then add more salt after you've added the dressing to the pasta).
Add well drained macaroni to a large mixing bowl along with eggs, bell pepper, carrots, celery and onion (if you like to have some color over you salad I like set aside some of the veggies to sprinkle over the top).
Pour dressing over top, add in parsley and toss mixture to evenly coat. Serve or store in refrigerator up to 1 day.
Notes: If you want an even richer, creamier dressing you can omit Greek yogurt, just use 1 cup mayonnaise and a few tablespoons milk to thin. If you don't have Dijon on hand, feel free to use a different type of mustard instead.Try it with other mix-ins. You don't have to use those listed. Some ideas include - minced baby dill pickles, pickle relish, bacon, green onions or chives, paprika, capers, cucumbers or tomatoes.
