I put together a one day ration as an experiment. It totaled 2365 calories and was pretty much ready to eat. Contents were
2 SPAM Slices (pouches)
Dried Apricots 6 Oz pouch
2 Tuna pouches
2 PopTarts
JIF To Go Peanut butter cup
Trailmix pouch
Cliff Bar
2 Chicken bouillon cubes
Chicken Noodle instant soup packet
4 drink packets
2 coffee packets
cost was around $12.60

Put it all in a larger size ziplock. Didn't have everything for a condiment pack which I would add: salt, pepper, TP, matches etc
