I am a social worker, and am in the car a good portion of the day. The gist is that I can't eat out any longer. It is undoing the whole reason that I am out in the car working and making money to be spending it on food.
The other thing is that I usually have clients with me in the car as well, and they are very often low-income (living on nothing but social security), and are usually hungry by the time I pick them up. I often wind up buying lunch for me and them as well. I do try to stick to dollar menu if I can though it is crazy unhealthy and still a waste of money when I know I can be packing healthy snacks that don't cost much instead.
I don't feel I can stop feeding my clients, even though it isn't required. I can't eat in front of them if I don't have something for them, but I have to eat regularly (I get low blood sugar easily), so that usually means I feed them too.
On top of it, hubby is a driver for a living, so he is in the car all the time too. Both of us really need to change our eating habits when we're not home.
So - the only solution I can think of is bringing a cooler with drinks (bottled water, thermoses with drinks from home, etc), and snacks that will still be good regardless of how long they're in the car, or what the weather is like (heat/cold/etc).
Any ideas? I would really love any suggestions you may have for non-perishables to keep in the car that taste good and don't cost a fortune. Thank you!
