Prep ingredients- keeping them separate to one another.
Fry sausage,until golden brown, in a little olive oil and set aside.
Add the onion, pancetta, carrot and celery and cook, stirring, for 5 minutes or until onion softens.
Add the zucchini, tomato, pearl barley and sausage and cook, stirring, for 2 minutes or until zucchini softens slightly.
Add the chicken stock and tomato paste and bring to the boil. Reduce heat to medium-low and cook, stirring occasionally, for 20 minutes or until barley is tender and soup thickens slightly. Taste and season with salt and pepper. (I didn't add salt- enough in the Proscuitto)
Add the spinach to the soup and stir to combine. Remove from heat. Ladle soup among serving bowls. Top with parmesan and serve immediately.
