Hi Kelly,
I’m afraid I would not be much help as far as balancing food nutrients requirements with homemade diets, but you may be able to buy a bag of freeze dried raw food (guaranteed to be balanced) just for these certain times. I don’t know if this is any easier, but I use premade raw when we travel (Stella and Chewy’s and Nature’s Variety) simply because it stores easier than a whole mess of odds and ends does. Of course that doesn’t eliminate the issue of cold storage. Check out some of the 5 star freeze dried bag foods though if you are looking for convenience.
