The one meal I remember from my Girl Scout camp days was called "Glop", & it was actually quite good - good enough for me to actually make it once I returned home. It wasn't made in a packet, but rather in a large dutch-oven-type pot over the campfire. Consisted of (if I recall correctly) rice, ground beef, canned stewed tomatoes, & cheese (American, I believe).
I have to admit that my "camp cuisine" has improved greatly from those days. As an adult camper, I bring along a little 2-burner propane stove, a large skillet, a saucepan with cover, & a cooler full of provisions that enable me to make omelettes or other breakfasts involving eggs & breakfast meats, grilled sandwiches for lunch, & the likes of turkey piccata, stirfries, or other such stuff for dinner. And I've learned to always bring extra, as 9 times out of 10 the people we go canoeing/camping with provision themselves with things like doughnuts for breakfast & hot dogs for dinner (which is fine unless that's all you're having 3 days in a row. . . ), & I end up feeling badly - lol!!
