MMmmm... Good stuff. Thank you for the link.
I remember when Boy Scout camping, making something like the Hobo Dinner in the link.
Except there were lots of onions in it too.
Ground beef, onions, chunked 'taters, carrots, some butter and salt pepper. Wrap (double wrap?) in tinfoil and throw it in the campfire for about 10 minutes. Poke it with a stick a few times to turn it over and cook another 10 minutes, or so...
Good, hot (somewhat greasy = better :-) food out under the stars with zero clean up.
Good Scouting memories.
Now-a-days I'd add an ice cold beer and call it "Fine-Dinning"!
