This is based on my other quickie, recipe #350071, but it contains no feta and no cream. Some evenings I am truly lazy when it comes to cooking dinner, but we are not fans of frozen or tinned vegs. So this is a life-saver, because no other side dish is needed when you make this, it's no-nonsense and very quick. Do not use swiss chard, because the leaves are too hard and tend to dry out on top: use the soft English spinach with the small leaves. I buy the conveniently cleaned spinach in the bags. Some small yoghurt containers are 5 oz (150g) and others are 6 ox (175 g). Won't make a difference which you use.
