Chop the onion and carrots. Slice the celery and pepper. Finely chop the chilli and garlic.
Heat the oil in a pan and sauté chopped vegetables gently, under cover, for 10 minutes. Stir in the curry powder, fry for a minute.
Pour in the vegetable broth, bring it to the boil and simmer, under cover, at a low temperature for about 30 minutes.
Drain the chickpeas and add them to the soup. Cook a further 5 minutes, then blend until you get a coarse textured, thick soup. Serve with fresh coriander leaves.
