Rinse barley and put them in a large saucepan with the vegetable broth. (if you can't find barley, you can also use Rice! In the same quantity!)
Dice all vegetables and add them to the saucepan.
Over medium fire, let the soup boil then simmer over low fire for 1-½ hours. While cooking, stir occasionally to avoid the vegetables from sticking at the bottom of the pan. In the middle of cooking, add parsley and basil. Season with salt and pepper. (adjust all seasoning amounts to your liking)
When it is cooked, turn off the fire then add Parmesan cheese and olive oil.
