The beans they listed have been staple foods for billions of people over thousands of years. Chickpea, lentils and pinto beans have histories going back 10,000 years in three of the oldest cultures on earth. The Babylonians ate chickpeas, the Indians of every flavor for millennia have eaten lentils. The “new” culture in the group is the Mesoamericans who only have five millennia of eating pinto beans. For most of the history of Latin America there was no domesticated animals the sole protein sources were beans, maize and squash aka the sisters is integral to the culture and history of Mesoamerican civilizations. With those three a human can be completely vegan the B12/6 is in the squash people were vegetarians except for wild turkey, Amarillo,iguana,and some cervids. Chickens, pigs and cattle wouldn’t come to the Americas until the Spaniards came in force in 1512. Bison is a North American species never made it out of South Texas into Mexico let alone Mesoamerica.
Nope.
Squash has NO, repeat NO B12.
So no.
You can not be completely vegan with those three foods. In fact there is no such thing a completely vegan. B12 comes only from animal products.

The word is deer. Lots of deer. Also rabbit and wild pigs were all eaten in Mexico.
And of course humans.
So they were vegetarians, except when they were eating meat.
Which they did as often as they could.
Like everyone else on the planet.
