If needed, make the meatballs or use store-bought. Prepare according to your needs.

Add the olive oil and onions to a soup pot over medium-high heat and sauté for 4-5 minutes.

Stir in the garlic and cook for 30 seconds.

Stir in the crushed tomatoes, beef broth, red bell pepper, Italian seasoning, crushed red pepper flakes, and meatballs. Increase the heat to high and bring it to a boil.

Add the pasta once it's boiling.

Reduce the heat and simmer it (covered, with the lid slightly open) for about 15 minutes or until the pasta is cooked, stirring occasionally.

Stir in the basil and season with salt & pepper as needed. Serve with parmesan grated over top if desired.
