What I eat depends on how much access to restocking there will be. When I can I shop daily and eat in a diner or other restaurant once a day or so. If off the grid I pack like I am backpacking. I have hated most of the freeze dried food I have tried except a few items like freeze dried veggies or fruit, but the meals usually suck so I don't use them. I did have some European ones that were really good. I got them from a hiker box when backpacking. Not sure of the brand (the label was in french). I am pretty sure they aren't sold in the US and were left by some European backpackers.
In general I seldom take much food from home and buy as I go. The exception would be if going into the back country, but I am more likely to go backpacking or canoe camping when I go off the grid..
