I like your pie better, but we are talking fast emergency food.
Right now there’s squirrels and rabbits around.
I cant make a GOOD crust without cold butter.
3:2:1 Flour:Fat:Water
Any fat. Oil even. It requires practice.
I have MREs for emergency food. And none of them involve tuna casserole without an included firearm for self termination before eating.
If it goes 3 days, I'm eating off the local economy or ecology. I got lotz o' stuff around I know how to make good meals out of. Fish, wild pig, squirrel... I don't eat the local rabbit. And I know which weed are good in salads, and which ones need cooked.
And there is local volunteer parsley, thyme, cliantro, basil, and rosemary within a one minute walk. Not cultivated, just growing.
I'll eat much better, and just as quickly off the land here. My prep supplies are more geared to things I CAN'T get here, like large bags of green coffee that I can roast.
