Things I could prep before a trip, possibly freeze and then put in the fridge just before departure would be great.
I full time and eating out gets old real fast.
Once a month I find a CG I really like and stay for a few days.
This is the stop that I set up and take my time and make chicken soup, chilli, noodles and red sauce and some sort of stew.
I then put them into containers and freeze them. It is SO nice to just pop one into the micro or a pot and have a nice
healthy home made meal in just minutes when ever I want. Even a quick stop at a rest area I can still have a nice hot meal before heading back out on the road.
I bought one of these camping stoves. Can put 2 big stock pots on at same time. Stove folds up flat for easy storage.

In your case if you made them at home and froze them they would take a few days to thaw out and then after they thaw out they would still be fresh to eat for several days. That would take you out a couple of days with prepared food.
You should look into those small electric fridges that "have a freezer". They are inexpensive. And there are always quite a few for sale cheap on Craigslist. I just bought a real nice mid size one with a good size fridge for $85 stainless steel front and all!
