If you live in a dense city, you may be better served by getting a commercial "emergency food supply" product. A 2-week food supply from one of the major suppliers of such products is about $125 and fits in 2 5-gallon buckets. Alternatively, you can get similar foods that come in #10 cans, they store nicely under a bed.

I use these products for backpacking and they will obviously never match a real home-cooked meal but they are decent in a pinch.

That covers you for food (you will need water), and just expanding your paper goods slightly should be plenty. You're not trying to become a "prepper", you just want to get through a bad week.
