Pasta Salad+Chicken freezer storage for a week?
I'd seriously doubt it going bad in 5 days if your fridge is set to a proper temperature and it was prepared with some semblance of proper sanitation. A vat of the stuff taken out of the fridge for serving 4 times, yes. An individual serving stored in the fridge the whole time, I doubt.

The pasta texture will get weird from freezing/thawing. Should not actually affect the flavor if it's properly sealed. You may or may not find the texture change acceptable. Your wife may or may not agree with you. 

As usual, experimentation will be your best guide as to whether you find it acceptable or not, so freeze one and don't freeze one and compare the two when you eat them.
