1. Slice the onions, grate the ginger, and crush the garlic
2. Heat the oil and fry the onion, ginger and garlic till golden brown ( I used a saucepan but a Karahi would be better)
3. Add the chilli powder, cumin, turmeric and coriander, fry for about a minute.
4. Add the spinach and salt to taste, cover and simmer for 15 minutes.
5. Stir in yogurt and heat through but do not allow to boil.
6. Serves 4--or 2 if you're hungry!
