While the meatballs are cooking, add onion, carrots, garlic, and olive oil to a large pot over medium heat.
1 cup white onion, 2 carrots, 2 garlic cloves, 1 Tablespoon olive oil
Stir and cook for 5-6 minutes until softened and fragrant.
Add the beef broth, crushed tomatoes, vegetable stock, Italian seasoning, and red pepper flakes.
4 cups beef broth, 20 ounce crushed tomatoes, 1 cup vegetable stock or chicken stock, 1 Tablespoon Italian seasoning, ½ teaspoon red pepper flakes
Bring the pot to a simmer (not a boil). Once they're out of the oven, add the meatballs, pasta, and red bell peppers.
1½ cup ditalini pasta, ½ cup red bell peppers
Simmer for 10 additional minutes, or until the pasta is al dente (just slightly underdone).
Top with fresh parsley or fresh basil as desired, and serve! Sprinkle with additional Parmesan cheese for a little extra cheesy goodness. Adjust to taste with additional salt and pepper as you prefer.
