Must say, back in my day we cooked it all on the river. Very little prep work. Course, our kitchen weighed like, 8,000 LBS. but that was mainly from all the cast iron stuff.
Now Georgie, as everyone knows, dragged out cases of canned whatever, and it was every person for themselves. The other outfitters tended to beans and stew; you know, easy stuff.
We kind of started a trend I think. We just didn't realize it at the time.
Doing omelets should be no biggie; trick is the fire on a good bed of coals, and a properly seasoned flat grill. Crank out 35-40 custom omelets in about 15 minutes, you know, once your grill was ready. If you're cooking with gas you got no excuse; just takes practice.
And yes, Lasagna on the creek is a real treat, but I could never get it to stay together; came out all ........... in piles. Needed some better engineering on it.
I will say, even the people I ran with back then who are still out there have moved to more prep before the trip, with seal a meal and what not. But, I always thought part of the camp fun was whipping out a birthday cake, or tasty omelets, or a killer steak and shrooms.
Naw, we coulda, but woulda got laughed off the creek.
