you can pretty much freeze anything. which is really nice b/c then you don't have to worry about leftovers spoiling or buying too much of a sale item. good housekeeping offers a great freezing guide. here are some of their tips: avoid any extra air, this prevents freezer burn, if you defrost using the microwave, fully cook the food before refreezing, and if you change your mind, make sure it's still partially frozen in order to refreeze.
