This is a very simple fresh vegetable soup, no cornflour involved and still the taste is good. Just courgette, onion, red pepper, celery and carrot, oxo vegetable stock, and black pepper of course.. This is more of a summer soup as it is very light and the carrot gives it the sweetness. I wouldn't change the vegetables for this as the sweet (carrot) salt (celery) bitter (red pepper) bitter (courgette) sweet (cooked onion) all balance out. The crusty bread mops up all the juices.
