If you could entertain your nostalgia and imagine an adult spaghetti O’s, with a rich tomato soup, chunks of browned spicy Italian sausage, some cooked orzo and lots of parm on top, this the soup. Heat another drizzle of oil and once it’s hot, add the onion, celery, carrot, fennel and a big few pinches of salt and pepper. Add the garlic, Italian seasoning, tomato paste and saute another minute or two.
