We love camping!! We leave Friday for a week in the mountains - can't wait!!
We have a little Coleman stove that we always bring. We pick up various meats along the way. Hamburgers, hot dogs, steak, chicken breast.... It's all good! Sometimes we have chili, Manwich, Hamburger Helper or Dinty Moore stew. Canned veggies are always easy, or instant mashed potatoes, or if you like rice there are lots of flavored rice mixes that only require water.
Basically anything that is in a box, in a can or is purchased that day is fair game for campground cooking!
For breakfast it's always pancakes and coffee. You can get little bottles of Bisquick pancake mix that you add water to, shake, and pour right into the pan. Very handy!! Or just bring a "just add water mix" and a bowl and wash up when you're done.
For dessert, well, it depends on how much work you want to put into it. My mother used to bring a dutch oven and actually baked cakes for us. Talk about spoiled!
But for me it's just not camping without S'mores and Jiffy Pop!
