Thanks so much for this suggestion. I was grating my zucchini, freezing it on a tray, then bagging it. Now I'm going to bag the grated zucchini, bag it, freeze it then use my Food Saver. I just shrink wrapped my kale, for green smoothies and did it from raw, and not freezing first (bagged enough for a large smoothie for 2 days). I recycle my washed FS bags I can't use any longer.
