How to Make Meatball Sub Soup
Prepare Meatballs: In a large bowl, combine ground beef, Italian bread crumbs, minced garlic, chopped parsley, crushed red pepper flakes, kosher salt, and freshly ground black pepper. Mix well and form the mixture into meatballs, about 1.5 inches in diameter.

Build Soup Base: Stir in the tomato paste, crushed tomatoes, low-sodium beef broth, and skim milk. Bring the mixture to a gentle simmer, allowing the flavors to meld together.
Combine: Return the cooked meatballs to the pot. Season with dried oregano, salt, and black pepper to taste. Let the soup simmer for about 20 minutes, allowing the meatballs to cook through and the flavors to deepen.

Meatball Sub Soup Recipe FAQs
What type of ground beef should I use for the meatballs?

What should I do if my meatballs aren t cooking through?
If you find your meatballs aren t cooking through, it s possible that they re too large or the heat was too low.
