Preheat the oven to 350 degrees Fahrenheit
In a bowl combine ground meat, breadcrumbs, eggs, fresh parsley, parmesan cheese, and season to taste with salt and pepper.
Place your meatballs on a greased baking sheet and place in the oven. Bake for 18 mins.
In a pan you can toast the acini de pepe pasta – this is optional – you can put the pasta in a dry pan over medium heat and toast it until it’s brown. Depending on the heat this can take about 5-7 mins. Set aside once brown.
While the meatballs are cooking in a pot add the sliced carrots, diced celery, diced mushrooms, onion, garlic and butter and simmer for about 12 mins.
Once the meatballs are cooked, drain the excess grease on a plate lined with a paper towel. You can set these aside until the pasta is cooked
Add the chicken broth and the pasta to the pot with the vegetables and cook the pasta according to the package.
Once the pasta is done you can add the meatballs to the soup. Let the meatballs simmer to warm through and serve when convenient.
