How To Freeze Zucchini: Blanch in UNSALTED water 1-2 minutes to inactivate enzymes that cause veggies to become mushy & discolored. Transfer immediately to water bath to stop cooking, then drain. For large amounts, do in several batches. Spread zucchini in single layer on wax-lined sheet tray to freeze before packing into bags. Keep toward back of freezer where temperature is more constant.
The next time you have green onions, don't throw away the white ends. Simply submerge them in a glass of water and place them in a sunny window. Your onions will begin to grow almost immediately and can be harvested almost indefinitely. We just use kitchen scissors to cut what we need for meals. I periodically empty out the water, rinse the roots off and give them fresh water.
