In a large skillet, add Italian meatballs, minced garlic, beef broth, Italian diced tomatoes, the jar of spaghetti sauce, Italian seasoning and a pinch of salt. Stir well.
Bring the mixture to a boil over the stove top on high heat. Then add pasta and push it under the liquid so it's covered entirely. Cover the skillet, reduce the heat to low, and allow it to simmer for about 20-25 minutes, stirring occasionally, until you can see that the liquids have reduced quite a bit and the pasta and meatballs are fork tender. Remove the skillet from the heat.
Stir together shredded mozzarella and grated parmesan. Add the cheese mixture to the top, cover with a lid, and allow it to sit for about 5 minutes, until the cheese is melted. Serve and enjoy!
