One of my options for a one-nighter is to get son involved in "building" foil hobo dinners a couple of days ahead. These are frozen for a couple days, then placed in plastic bag and wrapped in a towel. If you insulate them with the towel and put them in the middle of your pack they will be thawed just right for that night. I know you said gas stove... But hey, here's an opportunity to practice fire building skills.
