In a large soup pot, combine onion, bell pepper, tomatoes, garlic, and italian seasoning. Simmer until the onion and bell pepper soften.
Add the remaining ingredients including the water. Simmer for 10-15 minutes. Salt and pepper to taste.
Optional: Slice a loaf of french bread (or any type of artisan bread you prefer) and place in the oven at 350 degrees for approximately 10-15 minutes until slightly browned and crispy. Top each bowl of the soup with a slice of the bread and sprinkle with parmesean cheese.
