Jerky, string cheese or extra sharp cheddar and some small candy bars. I also bring two large Gatorade bottles if I'm on a longer trek, one if shorter. Really like that stuff.
A proven source of late season hunting lunch candy in my family was "Halloween Candy Tax" - where the Tax Man (me) would rummage through my kids Halloween bag the morning after Trick or Treat and take mostly Snickers, which have been mentioned in this thread previously several times. I dissected a Snickers for my kids, showing peanuts and convinced them that some health freak was pushing gross peanuts on kids, and that peanuts are not to be confused with real candy. I wanted my taxpayers (kids: 2) to maximize their candy income, so I could maximize my take without undue burden on their efforts, so I brought them to large neighborhoods where the houses are close together. I made a big deal out of it, telling them "no small talk! Just get the candy, yell 'thank you!' and run to the next house. Our goal is max candy, not fun. Stick and move, stick and move!"
I strongly recommend this strategy and really miss it since my kids are way past Halloween age.
