It really depends on how cold it is. When everyone is out trail riding and it's going to be cold I make a great beef stew with honey cornbread on the side. There are no left overs.
Keep in mind I cook these things when it is going to be dark about the time they get in and it's early fall or spring when the temps get cool.
If I am expecting hungry friends to come in late to set up I make a roast and veggies and let it slow simmer.
But there is nothing like building up the coals and cooking a steak over the coals and baking potatoes in the fire.
I also microwave some potatoes and carrots then chop them up with onion and wrap them in foil with a hamburger patty and make hobo dinners. Just toss them in the coals and pile some on top.
Get a cast iron dutch oven - they are awesome!!!
Everyone loves my campfire fried potatoes with onions in them.
Season a brisket and wrap it in a lot of folds of thick aluminum foil and bury it in the coals and leave it for 2 hours, turn it and just cover it again and let it slow cook until dinner... it falls apart and is sooo good.
You can have anything you want. We seldom even take hot dogs.
