In browsing here, I'm reminded of a meal that my older sisters made in 4-H many, many, moons ago. Hamburger patty, sliced or diced potato and carrot, some chopped onion if desired. Other veggies...
I refer to those as Cowboy Packets. Sometimes I add barbecue sauce. Or a pat of butter, maybe a grind or two from an Italian seasoning grinder.
When I was a kid at summer camp in Prince William Forest Park near Quantico, VA, we used to hike as a group to a nature lodge a few miles away. When we got there around lunchtime,the cooks would have a batch of those ready to go onto the fire.
Headed to Prince William FP in a couple of weeks, so maybe we'll have foil cooking that night.
