To get a good helping of natural fats with this meal you should add a salad with olives, avocado, and pine nuts and crushed walnuts. Add a few grapes and mesclun greens or lettuce, as well as a balsamic and olive oil dressing.
In a deep pan sauté the roughly chopped onion in a little olive oil until soft.
Add the rest of the vegetables - also roughly chopped, the juice and rind of the orange, the crushed coriander seeds and the broth - cook for about 20 minutes, or until vegetable are soft.
Blitz with a blender until liquidized and season to taste.
