For $40 you can get 25 lbs of pinto beans and 50 pounds of rice at Costco. That’ll easily feed one person for over two months, maybe three.
In “Once Upon a Time in China and America” with Jet Li, he and another Chinese man were in the old American West, eating beans next to a camp fire. They suffered, farted much, complained and realized the insanity of western movie food. The evacuation effort is worse (see thick, orange-brown paste, little visual there).
I’m not on food stamps, but I eat a lot of rice and bread with some vegetables, a little meat and much hot stuff. Pinto beans, not very often.
