I'm really curious about the "fake meat" products that exist in other countries. In the Netherlands, there's been enormous growth both in the number of vegetarians and in the number of "fake meat" products that have become widely available, and the quality of the latter has improved dramatically. Before, these products were mostly useful for the non-vegetarians wanting to prepare a meal for vegetarians without having to relearn how to do it (with actual vegetarians preferably preparing vegetarian-first meals, e.g. with nuts and beans rather than fake meat). However, nowadays these products have become so good that they're actually of added value to a meal in terms of taste.
Interestingly, they do not appear to place as much focus on matching actual meat as much as the foreign products that are usually the subject of articles like these. Instead, they merely have to taste good and have good texture - it doesn't matter if it's still somewhat different from actual meat (sometimes they even taste better).
At the forefront of this has been the Vegetarian Butcher (that's a brand name). They've recently been acquired by Unilever and will likely expand internationally more aggressively. I have the feeling that the Netherlands is friendlier to vegetarians, on average, than other Western countries, and if that will give them an advantage. Time will tell!
