I recently learned how to freeze excess produce. A friend told me about freezing freshly picked blueberries in a paper sack because she didn’t have time to wash and sort them first. When she retrieved them the next day they were beautifully frozen without any sticking together, all loose in the sack!
I now freeze everything that way, cut up fruits and vegetables, squash, even fresh herbs. Juicy berries don’t work as well but are still possible. Once frozen, rebag in freezer bags, where it’s easy to scoop out just what you need.
