I too work nights, I work one 14 and 2 13 hr shifts. I just take a few things and keep some snacks in my desk to munch on. I usually eat before I come in, then about midnight I eat "lunch" then I eat when I get home. I snack in between there if I am hungry or am not busy. lol. But I usually don't actually snack that often.
Mudpie -- How about those meals that all you got to do is add water and it heats up? I think Dinte Moore Makes them, they should be in the same aisle as beef stew/ravoli and stuff, not sure how "healthy" their meals are, but a thought.
BTW -- I thought of Kenny and George's song too when I saw this thread. lol.
Take care fellow Nightshifters!!!
