Mabel, I like the threads that you start!
I make hobos pretty much everytime I go camping. Wrap carrots, onions, potatoes and ground beef in tinfoil and cook it over the campfire. The juice from the hamburger makes delicious vegetables. Season it with salt and pepper. Sometimes I put honey in it.
If you want a sweet treat while camping, you can make icecream fairly easily. Just take the ingredients you would use to make icecream, stick them in a small foldgers can and put the lid on it. Stick the smaller can in a larger foldgers can, and fill up the empty space with ice. Roll the large can around until the ingredients inside have turned into icecream.
I put peanut butter and bananas on my s'mores.
If you are camping in cooler weather, soup is nice sometimes. I've made soup packets where I dehydrate vegetables and meat, put some seasonings in it, along with ramen noodles (or egg noodles, or whatever you want). Cook it in boiling water. The meat and vegetables will take form again after being put in water.
As far as gear goes, I've found hand held GPS units to be very helpful. Simply because I am directionally challenged. Bigtime. A rain fly for the tent. Ropes to tie your food up in the trees to keep the critters out. Insect repellent.
