I think my greatest single expense will be food, so in an effort to cut back on that cost, I plan on taking a bunch of pre-cooked and frozen meals in individual serving packages.
Placed in a cab fridge, these items should last a week or so. Figure three days to thaw and then good for another four.
You can microwave the frozen or semi-frozen items as well as ones that have thawed.
Some suggestions for meals that freeze well: Spagetti and other pasta dishes, stews, meat soups, chili, almost any casserole, etc.
Some other food items that can last far longer than a week are: Boiled eggs, breakfast bars, processed cheeses, some fruits such as apples.
I'm able to buy super or ultra pastuerized milk now that will last more than two weeks, so combine that with your favorite cereal and you've got breakfast.
Jerky and those dried fruit and nut mixes last a long time.
Buy your soda or fruit or water drinks at Walmart before leaving and add to fridge when space is available.
A small ice chest with a piece of dry ice in it will keep frozen items frozen for several days, extending the usable time for pre-frozen home-cooked meals.
Lot's of options and variety. For me personally, a good meal will probably be the highlight of my day.
If I'm on the road when I have necessary days off due to DOT driving time restrictions, I plan on taking alone one of those one-time use BBQ's and cooking a steak.
Just some ideas.
