I'm a retired single traveler and not a fan of cooking (I can some, but...). I like the parks rather than private campgrounds and sometimes get where I can't purchase a meal. I didn't get results sear...
There's always the loaded baked potato. If you make one too many you can use the baked potato to fry for the breakfast meal.
I am a single traveler as well. I do the crock pot, especially on cool or cold days. One especially is a chicken tortilla soup, I can forage all day on that.
