Sounds like there is a reason that pre-European foods are not eaten. They suck. Other than buffalo and venison, they had no decent meat, and they probably didn’t get that very often. Plains Indians couldn’t kill buffalo very easily until whites came with horses. Then, they were able to chase them and kill more of them, and they grew in size and population. The Indians in Mexico are tiny because they had no good source of meat, other than each other. The corn was crappy before whites came and used agricultural methods to make it bigger and better. In the southwest, they pounded acorns into a paste and made some real disgusting bread thing. There may have been a few good things to eat, but they were not plentiful or widespread.
you apparently have never eaten antelope or had a good mutton stew. more’s the shame
