Ah, think of all the money you will save in ice and veges that have gone off! It is certainly a worthwhile investment
When we've gone desert camping and are stuck for fridge space we often use dehydrated veges. They are not too bad, as long as you mix them with stuff, LOL. And I prefer them to the tinned ones.
Do you take a stove? You could make a mean pasta and sauce or fried rice and mix in your tinned and/or dehydrated veg into that...
ETA: Don't know if you're pregnant or not, but IME if you take enough rum and coke or vodka & tonic you don't care too much about food and how good/bad it tastes.
