As I understand it, back in the day people used to make s*it on a shingle with dehydrated beef. Jerky, a can of mushroom soup, some toast and that’s some good SHTF eatin.
Toast? If your toaster is working then the Scat missed the fan. Hardtack is edible, can substitute for target pigeons or be used to play hockey. That’s SHTF food!
We made it with homemade white sauce, which is easy to make.
