I’d recommend cured meats like smoked sausage or jerky along with crackers. I believe you can do cous cous without boiling the water too but I could be wrong there.
There are also some dehydrated backpacking meals that don’t require boiling the water. Usually they are the breakfast ones with powdered milk and granola and dehydrated fruits - they’re delicious and some of my favorite backpacking food!!
Just off the top of my head but I think you’re on the right path when it comes to sounding more eloquent. Poetry probably came from people messing around and playing with words to find what sounds interesting.
You’re already good to go on rhyming. So maybe just try for different rhyme schemes.
You might could also add other whatever-they’re -calleds like alliteration, consonance, metaphors, etc. Each of those are just a tools in the poet’s toolbox.
But what do I know!
