Typically, what do you eat when you're doing the long hauls?

I'm especially interested in input from those who (like me) tend to be frugal and don't eat a lot of junk foods. I tend to graze throughout the day, make my own trail mixes, etc.

What are some examples of your daily meal / snack intakes on your long haul (OTR) trips?

Would frozen foods hold out okay? I mean home made frozen foods in plastic containers -- would they thaw out and hold up okay? Is there enough room in the truck fridge for such things?

I welcome your comments and wisdom. Thank you.
