There are some joints of meat which are free, but I can't remember which have you done a search for Iceland you'll probably come up with loads of stuff.
I only buy quorn & veggies from Iceland as I'm not really a big meat eater.
Lamb in gravy is also free and they also do chicken breast with stuffing inside for 0.5 syns however I haven't managed to find it in my local Iceland. Apparently they are supposed to be really nice x
