*How long will roast zucchini with vinegar last?
If you end up with leftovers, you can store them for up to a day in the fridge. After that, you'll find that they're just too soggy to be very appetizing anymore. There are a few ways to use those leftovers, though. They can be sliced and added to a salad for an extra little bit of zip. And they can be rewarmed--a quick fry on the stovetop will do wonders for them.
