hell i would pay for that. high protein extra firm tofu is like 2.70/lb for me.
i get about 35g protein from 8oz of that tofu.
i eat salmon 2x a week but most of my diet is tofu and beans/lentils for protein.
i think it would be far ecologically and financially better to have tofu enhanced, so it meets nutritional needs at low cost.
and i personally find tofu a lot more flexible than any other food.
