Measure all of your spices except the BASIL into a small bowl and set aside. Heat olive oil in a large, heavy-bottomed kettle
or soup pot. Add the onion, potato, and mushrooms and cook over medium heat until soft and slightly brown. Toss in the OREGANO,
PEPPER, GARLIC, FENNEL, and CAYENNE and let them cook about 15 seconds. Pour in the vinegar and give it a stir. Add the tomatoes,
water, BEEF SOUP BASE and cooked meatballs and simmer for 30 minutes. Add the BASIL in the last 5 minutes of cooking time.
