That is indeed a good price, because per its protein content it is cheaper than chicken breast. Nevertheless you can still find meat that is cheaper than this, per its protein content, e.g. chicken gizzards, so it does not demonstrate the expected efficiency of eating directly vegetable proteins without passing them through animals. It is likely that something like seitan should be cheaper to produce than this, since I can do it at home for many times less money than that, but most commercial products for vegans are overpriced.
