Another view from the UK here...
As it happens, we camped at the weekend, and a meat and veg in foil was done.
Breakfasts we try and do a full english most mornings, fried bacon, sausage, egg, tomato, and cooked baked beans, maybe some black pudding. It's always a bit tricky with lots of people as it's almost all fried, and that takes up lots of space, some sometimes it's scrambled eggs instead.
Over the last few years we've got into dutch oven cooking more and more. We do one called South African Chicken Stew, no idea how authentically south african it is, as it's spiced with "cajun" spice, but anyway, always goes down well, as well as a chicken/chorizo in tomato thing we made that didn't have a recipe.
"raw biscuit dough from a can?"
I'm not sure we even have such a thing.
We did have a phase of making flatbreads over fires, making the dough, and cooking it on a flat bit of steel (or frying pan) over the fire.
Oh, pitta pocket pizzas, look like a car crash, usually taste great.
"Have your Scouts ever caught fish, then ate them that night for dinner?"
Yes, like CambridgeSkip says, sea fishing, over here, most lakes are small, and you go to all the trouble of catching a fish, then have to put it back, and if you did eat it, they'd probably taste like the bottom of a pond, not sure about rivers, fishing not my bag. Anyway, we did go sea fishing at summer camp a few years back, and caught enough fish for not just us, but all our neighbours too. We have a problem with American Signal Crayfish, escaped from captivity, and are spreading across the country rapidly, killing all the native species of crayfish...oversized, oversexed, and over here! Anyway, last year we camped at a local site with a river, put a trap out, and caught some, which you aren't legally allowed to put back, so we had to eat them
Just looked at last summer camps menu...
Gammon, veg, jacket potatoes
Minced beef cobbler
Fish & Chips (bought)
Beef Stroganoff and rice
It's all done from ingredients rather than pre-prepared stuff.
And yes, at some point, marshmallows have to be cooked on the fire.
Last week we had a curry night, but that was on gas in the hut, then again, no reason you couldn't do that on the fire in a dutch oven.
The main problem we have in the UK is you look on the internet for dutch oven recipes, and so it's all a cup of this, and a cup of that, whereas we tend to use weights and volumes. On the other hand, you can buy your american cup measures over here, and I guess on camp it might be easier, we certainly don't take scales, though we might have a measuring jug, so things can be a bit vague at times. And it's probably a personal thing, but all this "8 briquettes on the bottom, 12 on top" business? Stick it on the fire! stop mucking about!
