Add water camp food

I have built a car camping stuff collection designed to always be in my
truck and allow me to decide to 'stay the night' if I drive a ways to a
fishing hole and don't want to drive home .... the fishing to driving ratio
greatly improves by fishing another day before the long drive back.

I don't expect to always make the decision in advance and prepare for the
night's camping. It's been years since I tried and freeze dried
backpacking foods, but my memory of them is unpleasant.

So,

anybody got any good ideas for "add water" or "open a can" foods to throw in
this kit? ..... something that doesn't taste like cardboard, prefered
