Wash the spinach thoroughly and cut the rough stems off.
Cook the spinach in very little water in a covered pan for 5 mins then drain and chop.
Heat the olive oil over a medium to low heat and add the finely sliced garlic, sultanas and pine nuts. Fry gently for 2 - 3 mins, stirring all the time so that the pine nuts brown but do not burn. Add the spinach.
Mix all ingredients together and season with salt and pepper.
