In a medium bowl, combine the ground meat, breadcrumbs, egg, allspice, and nutmeg. Form into 1/2-inch diameter mini meatballs.
Heat olive oil in a large Dutch oven over medium heat. Brown the meatballs on all sides for approximately 6 minutes, then remove and set aside.
Add the onion, carrots, and celery to the same pot. Sauté for 5 minutes until vegetables begin to soften.
Pour in the beef broth and bring the mixture to a simmer.
Add the egg noodles and cook for 5 minutes.
Return the meatballs to the pot and continue to simmer for 5-7 minutes until the noodles are al dente and meatballs are fully cooked.
Reduce heat to low and stir in the heavy cream. Warm through without bringing to a boil.
Season with salt and pepper to taste and garnish with fresh parsley.
