> Current vegan/vegetarian incarnations of fake meat (Boca, Morningstar etc.) are typically actually not that healthy in terms of protein/amino acid content and sort of end up being eating a cake made of grains.

This is why I've stopped trying to find a meat substitute, they all fail in some way or another (they either don't taste right, don't have the right texture, or are far worse nutritionally than what they try to replace). I'm not a vegitarian, but I've found I prefer the Morningstar Spicy Black Bean Burger to a traditional beef patty - I like spicy foods and it has a nice texture I enjoy without feeling the need to compare it to beef. Also, the first ingredient is just plain black beans, there's some brown rice in to help as a binder but overall it has a fairly low amount of carbohydrates compared to other similar products (13g total, 4g of that is fiber).
