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...
We also do the going down the road crockpot meals. Prepare in the morning before take off, put the crockpot in the kitchen sink. Halfway there we add brocoli in a basket right on top of the meat dish which has carrots, potatoes, etc. Works great.
Also the Cathy Mitchell crockpot meals that use pastas, or cinnamon rolls also work well. You can find her on YouTube.
