Individual Foil Packet Dinners are easy and so convenient for campfires. Put meat on a large piece of heavy duty foil and top with sliced veggies. Add seasonings like salt, pepper, Worcestershire sauce, soy sauce, steak sauce to the meat and butter on the veggies. Fold foil over several times and crimp edges to seal. Just throw on the grill or in the coals. Of course, you can put the meat and veggies in separate packets, too.
You can make them at home ahead of time and even freeze them if you want to. Great advantage is that you can make them up with each person's preference. Just be sure to mark them so you won't have to open them before you cook them. Be sure to use heavy duty foil.
Ideas:
Ground beef patty
Boneless chicken breast
Sliced pork tenderloin
Smoked sausage
Onions, peppers, potatoes, zucchini, carrots, broccoli, asparagus, mushrooms, sugar snap peas
For Pizza Packets, you can top chicken or ground beef with pizza sauce, sliced pepperoni, onions, peppers, mozzarella cheese.
You can wrap potatoes in foil and throw them in the coals. Baked sweet potatoes are wonderful and cook much faster than white potatoes. I mix softened butter, brown sugar and a drop or two of vanilla to put on them after they have baked. Yummo! That mixture is also great to stuff in cored apples for a great dessert. Place apple in center of foil, bring up sides and twist to seal. Bake in the coals.
Rub softened butter on corn on the cob, sprinkle with salt and wrap in foil. Throw on the grill or in the coals.
You can make Baggie Omelets. Make them at home or on site. Break eggs into quart size Freezer baggie. Squish around to scramble them. Add chopped ham, onions, mushrooms, cheese, salt and pepper. Very important to squeeze all the air out. Drop into boiling pot of water. Boil for 10 to 12 minutes.
For breakfast, you can cook sausage and bacon at home and just reheat.
If all your food will be in coolers, making food at home ahead of time and freezing it is the way to go. You can make it days in advance and not be rushed. And you don't have to buy so much ice (which is so messy when it melts) to keep everything cold.
A food saver is perfect for freezing make ahead food, too.
Hollow out the inside of large onions and stuff with your favorite meatloaf recipe then add a pat of butter on top. Place in the center of a large piece of heavy duty foil. Bring the sides up and twist to seal. Cook on grill over coals, 45 minutes or so, depending on size. Great make at home and freeze meal.
Of course, nothing beats hamburgers, hot dogs, smoked sausage, BBQ chicken and ribs on the grill.
You can bake a ham at home, slice some thin for sandwiches. Slice some thick to heat on grill for breakfast meat or dinner meal with veggies.
A cast iron dutch oven is great for heating water, cooking and reheating.
You can make a lot of foods (beef stew, baked beans, chicken and rice, roast and gravy, chicken and dumplings, spaghetti) at home and freeze them then reheat them in a dutch oven over the campfire.
