Well done! That is really brilliant.
These mistakes sometimes work out for the better. I have no idea why but I made a similar mistake a few weeks ago.
I thought Tesco's Char grilled mediterranian (sp) veg was free.
I cooked a whole packet with quorn mince and it was so yum. I was going to post it here as it was so good and free but thought I would check the syns on line first befor I did. It was 35 syns for the pack! I was gutted as I already had my syn quota for the week. I went to class and found I lost a pound and a half anyway, which, for me, is a good loss.
I have really learned not to guess!
