Freeze green onions in water bottles - shake out the right amount and return to the freezer! This is great! You always have to buy so many green onions and recipes usually never call for more than 3 stalks.
Freeze avocados once theyre ripe! Great for when they go on sale, or when you need an avocado and theyre all too firm at the store. They keep for MONTHS this way! Who knew? Not that I ever need to do this :)..
