We used to make this on ww but it was called Swiss Bircher and you grated an apple into it and any other fruit you wanted like strawberries, rasps, blueberries and added the flavoured yogurt and it was real filling and we made up enough to do 2 days as it keeps ok in fridge. If it turns out too stodgy just add some more yogurt or splash of skimmed milk to thin or even bit of water.
