There is a lot of stuff like that, it is basically a 'transition' food, to ease them in, for example someone who is going vegetarian after years of being a carnivore. Sanitarium (now under the Vegi Delights label) made quite a few products, 'Not Bacon' (Obvious), 'Henchen (spelling) rolls' (Chicken), 'Smoked deli slices' (Meat slices) and on and on, there is quite a few different ones around.
