Hi Terry in Alabama, I have never frozen anything but tomatoes after breading. The tomatoes were soggy.since zuchinni has a lot of water, I'd be concerned that it would to, although you can buy it breaded & frozen. as for the summer squash, I've never frozen it. Why not try a couple of pieces of each and see how
it works?I know that this isn't much help,but lots of luck and let us know what you done
