Spaghetti Soup: Melt 1 tablespoon butter in 1 tablespoon olive oil in a large Dutch oven/stock pot. Add diced onions and saute for 3 minutes. Add carrots, celery and bell peppers and sauté for 2 minutes. Add garlic and red pepper flakes and sauté for 30 seconds.
Stir in all remaining ingredients under “Spaghetti Soup,” EXCEPT for the Parmesan and milk/half and half. Bring to boil, cover, then reduce to a low simmer for 15 minutes while you prepare the meatballs.
Meatballs: In a large bowl, add egg and gently whisk. Add all remaining Meatball Ingredients and mix until well combined. Roll mixture into 1 tablespoon size meatballs. Add meatballs to simmering soup and simmer for 8 minutes. Add spaghetti noodles and simmer over medium high heat for 10-12 minutes or until noodles are al dente.
Remove from heat, discard bay leaf and stir in Parmesan cheese until melted followed by milk/half and half. If you would like a less “chunky” soup, simply stir in additional chicken broth or water.
Garnish individual servings with freshly grated Parmesan and season with additional salt/pepper/red pepper to taste.
