White rice and beans in mylar bags with o2 absorbers. I use the gallon size bags and it's super easy. I found that the storage bins from Lowes, etc. are much more convenient than 5 gallon buckets. I can get about 13 gallon bags into one container as opposed to 3 in a 5 gallon bucket. Sawyer makes a nice gravity water filter setup. Asian markets sell little butane stoves and canisters which would be handy to cook in your apartment if the power or gas goes out.
