1. Put vegetable stock, red lentils, salt, pepper, onion and garlic in a large soup pot and bring to the boil. Once boiling, reduce to a simmer and cover.

2. Add carrot, green beans, leek, celery, capsicum, spinach, tomato then mushrooms to the pot as each is chopped. Add tomato paste. Keep pot covered and stir every 10 or so minutes until lentils have broken down.

3. Add corn kernels and simmer for 60 to 90 minutes. If the soup begins to dry out, add water.

4. Add parsley, oregano and basil then simmer for another 10 minutes.

5. Turn off stove, leave pot covered until cooled then refrigerate overnight (if you can wait that long). Re-heat to serve and add shaved Parmesan as a garnish.
