In a large dutch oven or soup pot, brown the Italian sausage over medium heat, until fully cooked. Drain any grease, leaving about 2 tablespoons in the pot.
Add the onion, celery and green pepper. Saute with sausage until onions are translucent.
Add the garlic and cook 1-2 minutes until garlic is super fragrant.
Stir in the beef broth, diced tomatoes, mushrooms, oregano, bay leaf, chili flakes, salt and pepper.
Reduce the heat to low and simmer 10-15 minutes. Taste and see if it needs more salt.
Remove the soup from the heat source and stir in the pasta. Or place pasta in bowl and top with soup.
Top the soup with grated Parmesan cheese, shredded mozzarella or fresh parsley.
