Ok I have a few to suggest! They might be odd but they are fun to make and good to eat!!
-I use this recipe at home but I think it would be great for camping! I know that a cast iron skillet is my best friend in the kitchen (something my grandmother taught me) and walmart sells the Lodge brand already seasoned! You can make this recipe the night before camping and it can reheat while you unpack and then use the pan for something else! I use a square pan about 8" wide but you can use a dutch oven or a regular round cast iron pan too!
It is the "impossibly easy barbeque beef pie" except I add a regular size can of bush's baked beans to the meat while it's cooking and I cook it all in the cast iron skillet (no pie plate) I also add cheddar cheese to the bisquick mix.
All you have to do is wipe out the pan or use a little scrub brush and some water and you can cook again in the pan.
-Also from my girl scout days we would take canned biscuits cut in half and stick them on a stick and cook over the fire. Spread some jelly or butter on them and you have "doughboys". Great for breakfast when you don't want to do a lot of work.
- One more! Breakfast in a bag!
Take a paper lunch bag (like the brown kind) but 2 slices of bacon in the bottom, crack an egg into the bag( weird I know but it works) you can sprinkle some cheese in or drop in a canned biscuit. I haven't tried it yet but maybe a scoop of bisquick biscuit mix in the bag would work. hook on a stick and hold over the fire until everything cooks. It takes about 10-15 min just don't burn the bag!
