For those vegetarians amongst you, there's a couple of varieties of Quorn down the bottom. There's also a range of vegan mock meats, including some very fishy-tasting fish, the chicken nuggets that Lord of the Fries uses, and many other exciting things! There's even cheap tempeh in there.
I'm super pleased by the close proximity to my house of all this mock meat, and given my recent discovery that the range stocked by my usual supermarket is no longer vegan, I'm pleased that so much of it is vegan! More reporting on specific kinds to follow, once I try more of them.
