Start by chopping your onion and mince your garlic.
In a pot, add your olive oil and onion. Put your pot over medium heat and sauté onions till they start to brown. At that time, add the garlic and sauté until fragrant.
Now you will chop you 6 celery sticks, make sure they are small. Add them to the pot.
Time to take your carrots, peel the skin off and the ends and chop them up small.
Sauté over medium heat until the vegetables are soft, stirring intermittently.
Chop your bushel of parsley leaves and add them to the soft vegetables and stir them in.
Add in your 8 cups of beef broth and 3 cups of marinara. Stir. Now you are going to bring the soup to a boil.
Once the soup is boiling add in your tiny noodles and stir. Cook the noodles for about 9 minutes [the time is depending on the type of pasta you are using].
After the 9 minutes your little pasta should be done [the time is depending on the type of pasta you are using], now you can stir in your meatballs, salt and pepper.
Let the soup rest for about an hour with the lid on.
And the soup is done!!! Top with fresh Parmesan and parsley and ENJOY!
