Peel, wash and dice the potatoes, cut the onion into rings and mash the garlic.
Heat the oil in a pan and sauté the onion and garlic for 2 minutes. Add the chilli, cumin and coriander powder and sauté for half a minute. Now deglaze with the vegetable stock, then add the potatoes and spinach. Bring to the boil once and simmer with the lid closed on reduced heat for 10 minutes until the potatoes are cooked.
