You just need to plan better.
There are things that you can bring that aren't tinned that will be fine for days without refrigeration. You can cook meats before you go, then just re-heat them at mealtime. You can carry pasta and some dried packaged sauces. You can carry some mung beans in a plastic bottle with holes in the lid, water them and shake out the water for a couple of days, and wallah, fresh bean sprouts.

They make a camping shower that's basically a hot water bottle with a shower head under it that you hang up from a tree branch.

Use hair and body wash instead of bars of soap, as it will avoid sticky disgusting bars of soap.

Carry along paper plates so you can just toss them in the fire after eating. Paper, not plastic or styrofoam.

Bring a deck of cards and play poker. If it's a mixed group, make it strip poker.

I didn't think anything could make camping worse.
But you've done it with "mung beans". They cause goatees, you know.

mung beans are the primary cause of sandals on people over the age of seven.
