Cut the carrots into small chunks and put them in a saucepan. Pour over the stock, add the cumin, then bring to a boil and cook for 10 minutes, until tender.
Drain the chickpeas and add to the soup. Cook for another 5 minutes.
Remove the skin of the roasted pepper and onion. Cut their flesh into strips and add these to the soup.
Squeeze out the garlic flesh from the skin and add to the soup together with the coriander leaves.
Using a stick blender, process the soup until you get a lightly textured soup. If it’s too thick, add more stock.
Reheat the soup, if needed and serve immediately.
