When you make this one-dish meal for a friend, we suggest delivering the cooked meatballs and sauce in a separate container from the noodles. Include instructions to reheat the meatballs and sauce in a medium saucepan over low heat for 10 minutes or until thoroughly heated. Noodles may be warmed in the microwave.
Combine the first 8 ingredients in a medium bowl. Shape mixture into 30 (1-inch) meatballs. Heat a large nonstick skillet coated with cooking spray over medium heat. Add meatballs; cook for 8 minutes, browning on all sides. Remove meatballs from pan.
Add mushrooms, carrot, and shallots to pan; sauté for 5 minutes. Stir in flour; cook 1 minute. Gradually add the consommé, stirring with a whisk; bring to a boil. Return meatballs to pan. Cover, reduce heat, and simmer 8 minutes. Add water; cook for 2 minutes. Remove from heat, and stir in the sour cream and parsley. Serve over pasta.
