When you tested food to see if it was agreeable, was it just for one meal, or did you do canned goods for several days in a row?
Sorry, I didn't answer your first question. It was mainly for one meal to see if it were palatable. I try to have enough of a variety to change the meat, starch, veggie every day. But you are right, I can see us getting tired of canned foods after a few days. But on the other hand, me and the mrs have our heads on straight.. We're not the illogical emotional type, we both handle stress very well.
My wife has been through difficult times when she was a child (food wise, she can eat rice and soy sauce 3 squares a day, been there done it). Me, I've always been a spoiled "Westerner" with meat and veggies at every meal. I think that is the main thing that will pull us through, our minds.. Food is just there to keep us alive... Just hope we never need to prove it...
