Add a can of chick peas to this recipe and you have a veggie meal for two.
Heat the oil in a large pan, add the onion, garlic and ginger, and fry for about 3 mins. Stir in the potatoes, chilli, spices and half a tsp salt and continue cooking and stirring for 5 mins more. Add a splash of water, cover, and cook for 8-10 mins.
Check the potatoes are ready by spearing with the point of a knife, and if they are, add the spinach and let it wilt into the pan. Take off the heat and serve.
