Begin this recipe by chopping/grating up the fresh onion, carrot, and celery into small pieces.
Cook the 1 ½ cups elbow macaroni in a large saucepan according to the package instructions and drain off all the water once finished. Transfer the cooked pasta to a separate large bowl.
To the same large mixing bowl while the pasta is still warm, gently stir in the ½ cup carrot, 3 tablespoons onion, 1 stalk celery, 3 tablespoons pickle relish, and ⅔ cup mayonnaise.
Add ½ teaspoon salt and ¼ teaspoon ground black pepper before stirring to thoroughly distribute.
Serve the macaroni salad immediately while it is still warm. Enjoy!
Store any leftovers in the refrigerator in an airtight container for up to 4 days. When ready to serve, simply serve cold straight from the fridge.

This macaroni salad can be served cold for a cold pasta salad. Simply prepare in advance and store in the refrigerator before serving.
