When camping, I cook like I do at home-grilling everything or using a crock pot (roasts) to go on a day trip away from camp. I use a small portable covered propane gas grill. Hot dogs get old quick!
If you want to lay back and drink and not hafta cook later, (or are going away from camp) we take ground beef, diced potatoes, carrots, onions, summer squash and zuccinni, and salt and pepper, maybe a dash of garlic powder, then double wrap it in heavy duty foil ('Nad Guard).
Make the packets about 1 pound total for each, about 1/3 meat-pattied. Spread the fire open exposing some coals and lay them in. I flip them in about 7-10 mins. and pull one at about 15-depending on how hot the fire is, how much veggies I put in the particular packets, etc. Dump on ketchup from fast food packets if out and way from camp, (like at beach) or eat plain. Best to err on the raw side until you get the hang of cooking in a fire, things can cook extremely fast if it's a real hot fire. You're gonna need hot pads, mitten type, and either a long stick and/or tongs.
