I tried making a beef stroganoff the other night and replaced the cream with natural yogurt, the flavours were there but I found it curdled a bit which put me off entirely, must work out how many syns the weight watchers cream is to try instead x x
Or try the mushroom stroganoff one and replace with beef.
Beef stroganoff is something you can pretty much just google any beef stroganoff recipe and adapt it to make it SW friendly by omitting alcohol, replacing cream with yoghurt etc etc etc...
