I got to experiment with my food storage about a month ago. I crushed a finger at the end of April, and didn't have transportation til mid July. I got to go to a store twice, but otherwise I lived off what I had. I didn't make an appreciable dent in my stored food. Aside from missing fresh vegetables, there was no end in sight when I'd run out of food.
A couple notes... My canned vegetables weren't varied enough. I still need to widen the range I have on hand. Sliced carrots work really well in a can, and I think I'd like to get more spinach and greens.
Knäckebröd(crispbread) goes a long way for a bread replacement. Slices of cheese and bake it in an oven, crumble it into soup, use flavored/sweetened nut butters for dessert... It's pretty versatile. If it gets stale, a short time in the toaster over refreshes it. I made a post in P&N about the tariffs fucking me, and not being able to get julknäcke this year. It isn't released til early winter, but I think I might make an order of regular bread before the end of this month. Grocery Outlet had some last year, and I bought a bunch, so they should get more if it becomes available, but that isn't something you can count on. Shipping is ZOMG expensive, and not being able to get julknäcke takes a lot of the value away, but I think it'll be worth having on hand, even if I can't get exactly what I want.
Anyone even vaguely interested, Wasa is knäckebröd. It's the worst example of it I've had(Leksands is the best), but you can get it at just about any decent US grocery.
