I'm a little iffy about Quorn. I eat quorn at Wetherspoons, on the occasional Saturday breakfast treat, but otherwise I try to resist their lure. It's nice to have convenience food every now and then but it has the same effect as most heavily processed food product; a nasty aftertaste, oily, salty and cloying.
Cauldron foods are available in my local Somerfields and they're pleasant enough, but SO expensive. I've taken to making veggie sausages from tofu bulked out with mushrooms and breadcrumbs, and flavoured with herbs, a little red wine, if I've got some in, tomato paste, etc. The resulting goo fries well and is rather yummy, particularly in a sani with ketchup, or as balls put into a tomato sauce for pasta. I've been meaning to wrap a lump of it in pastry and bake it and see how that works, but haven't got round to that. It'll even grill if it's made dry enough then brushed with oil. I haven't made it look pretty yet, but I'll think of something. A pack of Tofu, even the hippy organic stuff from Somerset that they sell in Holland and Barrett, is cheaper than five 'sausages' and half a pack is all my concoction requires to feed the two of us.
Somebody told me Linda Mcartney snags have got better recently but they used to be so unpleasant I haven't tried them for years.
